How the bell lifts the sternum, and why the fit decides everything.

Watch this before you buy a generic bell off a marketplace. The fit is the whole game.

01 / Is this you?

You were told surgery is the
only way. It isn't.

Six questions. If you're nodding at most of them, you're on the right page.

You hate taking your shirt off
The beach, the pool, getting changed, being seen, you've built your whole life around hiding your chest.
Surgery terrifies you (and rightly so)
A metal bar wedged behind your sternum, general anaesthetic, weeks of pain, real risk.
You can't afford a $50,000 operation
Even with insurance, the cost, the time off work, and the recovery put surgery out of reach for most people.
You tried a cheap bell and it did nothing
Generic round bells fit no one.
You've been told you're 'too old'
Adults in their 30s, 40s, 50s and even 60s correct their chests with consistent vacuum bell use.
Nobody gave you a real plan
How long per day? How much suction? When to go overnight? Left guessing, people quit in week three, right before the lift becomes visible. The 90-day plan removes the guesswork.
The truth the surgical route doesn't advertise

You don't need to be cut open.
You need the right pull.

Peer-reviewed studies spanning 30+ years show the vacuum bell lifts the sternum, and with daily use, the lift holds. The variable is the right device and the right plan.

29/29 patients lifted in one study
>1 cm held after 3 months daily
30+ yrs of peer-reviewed research
02 / The device

Meet the
vacuum bell.

A clear, 3D-printed dome that seals to your chest and lifts the sternum with nothing but negative pressure. Drag it to inspect the exact device that ships to you.
03 / How it works

Steady pull.
Reshaped cartilage.

One physical law, applied for 30+ years: bone and cartilage remodel under directed, sustained load (Wolff's Law). The bell supplies that load, without a scalpel.

Custom vacuum bell sealed to the chest, lifting the sternum
Firm, never painful
Suction you control
Hand pump + release clip, you set the pull, session by session
30+ yrs of clinical research
The custom 3D-printed bell, shaped to one chest
01 / Seal

A seal only a
custom fit can make

Every gram of lift depends on the airtight seal. Your bell is 3D-printed taller and oval, shaped to your depression, so the suction lands exactly on the area that needs to move, with no leaks, no nipple overlap, and no wasted pressure. It's also why generic round bells fail: they seal on almost nobody.

14.8× higher odds of excellent correction when the chest is flexible and the fit is right · 2025 cohort odds ratio

02 / Lift

Suction raises the sternum,
and you watch it happen

Pump until you feel firm tension, lock the clip, and the dip visibly rises through the clear window. At first the lift lasts a few hours after each session, that in-session elevation is the raw material of correction.

21→8 mm average chest-depth reduction with consistent use · AlShammari 2026
The corrected chest, held between sessions
03 / Remodel

Repetition makes
the lift permanent

Under repeated, directed load, cartilage and bone remodel. Session after session the lift holds longer, until it stops springing back, one analysis found over 1 cm of permanent lift after three months of daily use, and 50–70% of compliant users show measurable sternal elevation.

+1.7 mm extra depth reduction for each added daily hour of wear · 240-patient cohort

The variable that decides your result isn't age. It's hours.

10 min first sessions
2 h/day working dose
6–8 h overnight · advanced

Wear time of 28+ hours a week is the single strongest predictor of correction, full citations in the evidence section below.

04 / Instructions

How to use it.

Four steps. A few minutes to learn, and the routine is yours for good.

Pressing the vacuum bell onto the chest to create the seal
STEP 01
Press hard to seal

Place the vacuum bell over your sunken chest.

Press down firmly with both hands until the silicone contours to your skin.

You'll feel it seal. It's a good sign if it stays in place for 3-4 seconds without pumping.

Pumping the vacuum bell until the chest rises under tension
STEP 02
Pump until you feel tension

Start pumping slowly. With each pump, your chest rises, often for the first time in your life.

Keep going until you feel strong tension (not pain). That's where the magic happens.

Your ribs shift. Your chest opens. You breathe deeper.

Vacuum bell locked in place and holding on its own
STEP 03
Lock it in and relax

Tighten the air clip fully. This locks the vacuum in place.

Disconnect the pump. The bell stays attached by itself.

Start with 10 minutes. Over time, increase to 2+ hours daily (or wear overnight while sleeping).

Releasing the vacuum and lifting off the bell to reveal the elevated chest
STEP 04
Release and see results

Loosen the clip. Press the release button. The vacuum fades. Gently lift off the bell.

Your pectus area is visibly elevated. Higher than before.

At first, it lasts a few hours. With consistent use, it becomes permanent.

08 / The research

What does the
science say?

If you're still wondering if it really works, you're not alone. But, the answer is clear. Scientific studies and real-world results say both yes, and the benefits are plenty.

In a case study by Eckart Klobe, inventor of the vacuum bell, a 61-year-old man with a 4 cm chest dent successfully improved his pectus using the vacuum bell.

The study was published in Orthopadie Technik (OT), the leading orthopedic journal in Germany, Austria and Switzerland, regularly read by 87% of professionals.

He used a 26 cm vacuum bell for 3-4 hours daily, split into 2-3 sessions. Over time, both short-term and long-term improvements were clearly seen.

From the research
Even at 61, the sunken chest depth reduced with consistent use, showing this works not just for kids and teens, but adults too.
Chart of the 61-year-old patient's chest depth over 9,600 hours of vacuum bell use
His results over 9,600 hours (around one year). The upper red square is the chest shape immediately after device use (temporary); the lower red square is the permanent improvement measured before use.

Graph showing chest elevation within 2 minutes 33 seconds and 6 pumps of the hand pump
The same patient saw noticeable chest elevation within just 2 minutes and 33 seconds, using only 6 pumps. The yellow spikes are the pumps; they raise the vacuum pressure (red), and the chest starts lifting almost immediately (blue).

    Nine kilos in six months. Building the muscle around the ridge did more for how it looks than the years I spent hiding it under loose shirts.

Before You Start · Straight Answers

What people ask
before they begin.

The four that come up most, answered the same way I would answer them on a call.

Take the 60-second quiz
How long before I see a change? +

Posture and breathing shift first - most people feel that inside the first few weeks. Visible chest change is slower. In the case log above, Milo saw his first real change at 2 months, Ian at 6, Liam at 9. The programs run 16 weeks because that is roughly how long it takes for the training to show up in the mirror.

Am I too old for this to work? +

Almost certainly not. The clients documented on this page were 22 to 32 when they started. Cartilage does stiffen with age, so progress is slower the older you are - but slower is not the same as stopped. What changes is the timeline, not whether it is worth doing.

Do I need a gym, or can I do this at home? +

Either works. Every program ships with a gym track and a no-equipment track for the same 16 weeks, so you pick the one that matches what you actually have access to. You can switch between them mid-program without losing your place.

Pectus excavatum, carinatum, rib flare - is it the same plan? +

No, and that matters. A sunken chest and a protruding chest need close to opposite work, and rib flare often rides along with both. There is a separate program for each. If you are not sure which one you have, the 60-second quiz sorts it out and points you at the right starting place.

11 / Picture the day it clicks

The chest you stopped
believing you could have.

Correction is gradual, a few hours at first, then it starts to hold. Here's what people tell me changes when it does.

The custom bell, built to your chest
The custom bell, built to your chest
You take your shirt off without a thought
The pool, the beach, the bedroom, the changing room, the flinch that ran your life for years just… stops.
You breathe deeper
As the chest lifts, the lungs have room to expand. People describe their first full breath as a genuine shock.
Tight shirts stop betraying you
The dent that showed through every fitted shirt flattens. You wear what you want, not what hides you.
You stop performing confidence and start feeling it
There's a particular weight that lifts when the thing you've hidden for a decade is simply gone.
You did it on your own terms
No doctors, no hospital, no recovery ward. You fixed it at home, in private, and nobody had to know.
You stop wondering "what if"
No more lying awake weighing a surgery you're scared of against doing nothing. You chose the third option, and it worked.
12 / Why this bell beats the marketplace ones

Five things a $30 bell
will never give you.

Other brands sell 3 or 4 generic sizes and a thin leaflet. Get the size wrong and you get nipple pain, air leaks and regret. Every bell I make is built for one chest: yours.

Custom 3D technology

Custom 3D technology

A taller, oval-shaped bell 3D-printed to target only your sunken area, nothing wasted. Stronger, more focused lift, a better airtight seal, no nipple irritation, and it handles asymmetric pectus.

Built to last

Built to last

A solid, one-piece 3D-printed body. No glued parts that fail, no fragile glass that shatters when dropped. It survives real life so your routine never stops.

Crystal-clear, unbreakable window

Crystal-clear, unbreakable window

Watch every millimetre of lift happen in real time through a glass-like window that's stronger than glass. Won't crack, fog or yellow, stays clear for years, not weeks.

Safe, comfortable medical silicone

Safe, comfortable medical silicone

FDA-certified, medical-grade, hypoallergenic silicone, the same family used in medical equipment. Zero itch, molds to your shape, holds up under vacuum pressure, hour after hour.

Strong suction pump, included, plus a spare

Strong suction pump, included, plus a spare

The professional-grade hand pump comes in the box from day one. No upsells, no hidden costs, and a backup pump too, because if the pump dies, your whole routine stops.

13 / Nine reasons to skip the operating table

What surgery costs you,
this gives back.

Painless
No cutting. No metal bars. Just gentle suction that works quietly while you live your life.
Save a fortune
Surgery can cost $50,000.
No recovery
Start today, work tomorrow.
No implants
Nothing goes inside your body.
Zero surgical risk
No anaesthesia. No complications. No surgeon’s slip. Nothing to go wrong on an operating table.
No age limit
Told you’re too old for surgery?
No waiting lists
Order today, wear it within a week.
No hospital needed
Fix it at home. In private. On your own schedule. Nobody ever has to know.
Works overnight
Advanced users wear it while they sleep, correcting their chest passively, 6–8 hours a night.
Side by side

Same lift. None of what surgery adds on top.

Mihail Veleski, founder of Mr. Pectus
I had it myself
From the founder

I'm not writing this as a doctor looking at a scan. I had the sunken chest, the flared ribs, the shirt that stayed on at the pool, and nobody could tell me what actually works.

Everything on this page exists because I needed it to exist ten years ago.

14 / Who built this

I had it. I fixed it.
Now I help you do the same.

I'm Mihail Veleski. Pale, skinny, sunken chest, flared ribs, I had it all, and it wrecked my confidence. Years of consistent, non-surgical training made my deformity unnoticeable.

I founded Mr. Pectus to give people the exact path I had to find the hard way, tested on my own body first, then refined every time someone hit a wall I had not planned for.

15 / Made to fit you

Measured to your chest,
not off a shelf.

There are no generic sizes here. You take one measurement, send it to me, and I 3D-print a bell to your exact chest. Two minutes of work for a fit no marketplace bell can match.

STEP 01
Measure nipple to nipple
Grab a ruler and measure from the inside edge of your left nipple to the inside edge of your right.
STEP 02
Send me the measurement
Order, then send me the number by email, Instagram DM or WhatsApp.
STEP 03
I 3D-print it to your chest
Your bell is printed taller and oval, shaped to your depression so the suction lands exactly where it should, including for asymmetric chests.
STEP 04
Fit, seal and first session
Place it, pump until you feel firm tension (never pain), lock the clip and watch the lift.

Unsure between two sizes? Go larger, a larger bell captures more of the chest wall, which matters most for deeper and asymmetric depressions. Message me your measurement and I’ll confirm before I print.

16 / Honest assessment

Let's be honest about
who this is for.

It's for you if
You want to avoid surgery
You have a sunken chest and would rather not be cut open for it
Daily wear is realistic
Consistent sessions, building toward wearing it overnight
Privately, at home
Instead of a referral, a waiting list and a hospital stay
Built to your chest
Scanned and made for your dimensions, not a size picked off a chart
You want a real plan
And direct access to the person who made the device, not a leaflet
It's not for you if
You want it overnight
Correction here is gradual and earned, session by session
A severe cardiac case
If a doctor has flagged it for surgical review, start there instead
You won't measure or wear it
The device only works for the hours it is actually on your chest
You want the cheapest bell
A generic one costs less and fits worse; that trade is a real one

A vacuum bell is a correction tool, not a medical override. If a doctor has flagged a cardiac or severe structural concern, clear it with them first.

18 / FAQ

Common questions.

Does it actually work, or is surgery really the only fix? +

It works. Peer-reviewed studies over 30+ years show the vacuum bell lifts the sternum; one analysis found permanent lift over 1cm after three months of daily use, and others report 50–70% success in compliant users. The Nuss operation (the surgery that slides a metal bar behind the ribs to push the chest out) is effective, but research increasingly treats the vacuum bell as a real, comparable alternative, especially with a proper fit and a consistent protocol.

Will it work for me as an adult? +

Yes. Adults in their 30s, 40s, 50s and even 60s have achieved great results. Teens respond faster because their cartilage is softer, but age is never the dealbreaker, consistency is. The 90-day plan adapts the progression to age.

How long until I see results? +

Mild cases often see change within 1–6 months; deeper cases can take up to a year. At first the lift lasts a few hours after a session; with consistent daily use it starts to hold. Depth of the dent and daily consistency are the two biggest factors.

How long do I wear it each day? +

Start gentle: about 10 minutes twice a day. Build up to a minimum of 2 hours daily, roughly an hour in the morning and an hour in the evening. Advanced users wear it overnight for 6–8 hours. The plan walks you through the exact build-up so you never overdo it.

Does it hurt? What about redness? +

It shouldn't hurt. A slight tightness or pulling is the suction working. Sharp pain means you're pumping too hard, ease off. Light redness and a ring mark are normal; bruising or deep red patches mean the suction is too strong or the session too long, so reduce intensity and take a day off.

I have an asymmetric chest, will it still fit? +

Yes. Because your bell is 3D-printed to your measurement, it can be shaped and positioned for off-centre and asymmetric depressions. As long as you get a good seal and a visible lift, you’re using it correctly. Tell me about your chest when you send your measurement.

Is there a minimum age? +

There’s no lower age limit for the device itself, a 2022 study in Frontiers in Pediatrics found it safe and effective even for young children, who respond faster thanks to more flexible cartilage. For kids, involve your paediatrician and use the gentlest settings.

Why custom-fitted instead of a cheap bell from Amazon? +

Because the entire mechanism depends on the seal. A bell that doesn't match your chest contour leaks suction, needs over-pumping to hold, and bruises the edges while under-treating the dip. One built to your measurements seals at comfortable pressure, which is what makes daily consistency, and therefore results, actually possible.

How do I measure myself, what if I get it wrong? +

The guided measuring process takes about five minutes with a tape measure and the instructions I send you. Every measurement is checked personally before your bell is built, if something looks off, I contact you and we sort it before anything is made.

Do I get instructions, or just the device? +

You get the full 90-day protocol with it, session build-up, suction guidance, and what to expect phase by phase. The bell is the tool; the plan is what makes it work. And if you want the deep-dive on technique, the Vacuum Bell Mastery Guide pairs with it.

Can I train and use the bell in the same day? +

Yes, they compound. Training expands and strengthens the chest the bell is lifting; most people schedule sessions around workouts (the plan shows how). The PE course covers the full pairing if you want the complete system.

My dip is deep, will a bell even move it? +

Deeper dips take longer and progress in smaller steps, that's the honest answer. The custom fit matters most in exactly these cases, because a standard bell often can't seal on a deep or asymmetric dip at all. Tell me about your chest when you order and I'll give you a straight read on expectations.

Does it ship to my country? +

Worldwide, tracked. It ships 5–7 days after your measurements are confirmed, and you get the tracking number as soon as it leaves.

What happens after I order? +

You send your measurements, the guided process takes about five minutes, then your bell is built to them and ships in 5–7 days with tracking. If a measurement looks off, I contact you personally before building.

What if it doesn’t work for me? +

You’re covered by a 30-day, no-questions-asked, 100% money-back guarantee. If the device isn’t right for your anatomy or you don’t feel you’ve received great value, message me within 30 days and I’ll refund you in full. The fit, the kit and the plan exist precisely so it does work.
