Jail Bird

The JAIL BIRD male chastity device is our most popular design. The stainless steel bars are very rigid. They will not bend or pinch. Combines comfort with security, and great looks. Has a very low profile that is easy to hide under clothing and is perfect for 24/7/365 wear.

The open design makes it easy to clean without removing the cage. This makes it possible to wear the device indefinitely. Great for Internet or long-distance relationships.

Excellent quality and service

Apr 05, 2014 by MisterE

I had been in and out of polycarbonate for years before finally plumping to spend money on a metal device. The plastic models were off puttingly smelly for my wife after a couple of days, and I was forever getting abrasions from the unforgiving contact. So I was always out to clean or heal and Mrs E never felt she was really in full control. The Jail Bird has completely resolved this - it was exactly as ordered, fits perfectly, and has been on none-stop since we received it early March.

I can't speak highly enough of MM who helped out by email with sizing and customising details, or of the quality of the product,

This is the second cage I have purchased from Mature Metal. Their quality and service is amazing! I purchased the first Jail Bird for my husband after I had him wear a plastic cage for several months. I selected the Jail Bird because I like the looks.

I recommend first time cage buyers avoid the plastic cage, measure as recommended and eliminate major problems not found with a Mature Metal cage.

The measurements from the plastic cage were used to fit the first Jail Bird. It fit OK but after a year wearing the Jail Bird, his scrotum stretched. This stretching made the cage not fit well.

This time, I took exact measurements as recommended. The fit is perfect. He is comfortable and I can enjoy the purpose of the cage without his complaint of fit and comfort.

If I could change the past, I would have bought here first, used the sizing rings and saved the problems of the plastic cage...such as hygiene, poor fit and unacceptable discomfort.

Jail Bird is the only way to go!

I started my chastity journey in a plastic device, as most guys do. It was okay to get an idea what chastity was all about, but when it split and pinched me in a very sensitive area my wife/keyholder wasn't happy! A short time later I bought the short version of the plastic device and it was somewhat more comfortable, but my wife was always worried that it might split like the first one and she wouldn't be there to release me. When she decided she preferred me being locked fulltime and I agreed to it I decided it was time for a custom fitted device and got her permission to shop for one. The Jail Bird seemed to be what I was looking for and after showing it to my wife she said "Get it ordered!" It came in last week and she immediately locked me in it. She loves how it looks and since she is a nurse she also likes the open design over the plastic devices, as it's much more hygienic. After a week in the Jail Bird I can say that it is MUCH more comfortable than the plastic devices and it is a LOT easier to keep clean! The comfort level is so much better than the other devices, which is good since my wife only unlocks me for her pleasure and once a week to shave! We also opted for the security screw rather than the padlock, and it was a good decision. The screw is much more compact than a padlock and you don't have to deal with something flopping around and making strange noises if you spend a lot of time wearing only gym shorts like I do. Having a mechanical background I can honestly say you aren't going to go to the hardware store and find something to fit the keyhole on these screws! Overall I have to give the Jail Bird 5 stars and two thumbs up, it was worth every dime we spent on it and probably more! Mature Metal's customer service was also great. I made a slight change to my sizing a couple of weeks after ordering it and Mistress MM handled that with no drama whatsoever. I also received the Jail Bird a couple of weeks sooner than expected, which was a plus! Thank you Mature Metal for a quality device!

Superb Product

Feb 19, 2014 by StevenS

I have tried quite a few devices over the last few years cb2000,3000.6000 and 6000s as well as a silicone device and cheap chinese metal. Without doubt all pale by comparison to the Jailbird. Once you know chastity is for you don't waste time and money on inferior devices. A one time investment in a proper device custom made is a no brainer. Both myself and my wife LOVE the Jailbird. It's in a different league from plastic and silicone devices. If your serious about a chastity device do it once and do it right. I would recommend Mature Metal to anyone superb product and perfect service.

Perfect for Permanent Chastity

Feb 19, 2014 by cryanisback

My wife/mistress and I have progressed from ordinary chastity with a CB-6000 to permanent chastity using a Mature Metal Jailbird. I've now had the MM device for 13 months and the, other than hygienic (waxing mostly) removal, it's been on 24x7. Now that my wife/mistress has invested in a dozen or so laser hair removal treatments for me, I'm locked away, probably for good - and that's what I want. While I've only had the two devices, I feel that once you find the perfect device, why experiment? The MM Jailbird is superb. I do heavy outside work on our property almost daily, workout, ride a bike, job, swim, hot tub, sauna - everything I did years ago without chastity - and find that the MM Jailbird is now a part of my body and skin. My wife/mistress refers to it as my "jewelry" as it's so attractive, it looks like I've adorned my penis with a beautiful stainless steel bracelet. Since I don't use it for anything else, it might as well be a place where I put my jewelry. Congratulations to MM for designing and producing such a fantastic device.

This is the perfect device

Cannot tell you how much I love my Jailbird. This device is the most secure, most comfortable CB I have ever found. The arousal and frustration this device causes (my wives makes certain of it) keeps me on edge for weeks at a time. This is the only way to live for me. Thanks MM

Jailbird is the perfect device

Nov 04, 2013 by Marty

I loved my first one so much, I ordered another. The fit is perfect and allows me to wear it for multiple weeks. Clean up is simple and the frustration is better than ever. Thanks to the team at MM of reputing such quality work into this devious device.

Locked For Her

Oct 31, 2013 by John

This is the best chastity device I have used. Have been using chastity for about 8 years. Started with the curve then the cb6000 then the cb6000s and finally I purchased the Jail Bird from Mature Metal. WOW talk about comfortable there is no comparison. I have had the Jail Bird on 24-7 for two weeks. The best part is ease of keeping it clean with the design of the bars all you have to do is shower and your clean. No longer do you have to try to get soap inside to get yourself clean and drying is a snap. My wife now can take the security key with her and I stay Locked For Her. I highly recommend the Jail Bird. Thanks Mature Metal

Arguably in the top 3 chastity devices in existence.

Oct 12, 2013 by Jakey

This chastity cage is the bees-nees, I mean it. My journey through chastity started when I was 16 years old, 4 years ago. A sir of mine got me the cb-3000s, and upon putting it on once, I knew I couldn't wear it outside of my bedroom--as I wear tight pants it and just wouldn't work. A year and a half later, give or take a few months, my new Sir--and current best friend--purchased a Birdlocked for me. I thought that it was the smallest cage you could possibly get, in terms of discretion. I needed my cage to be invisible under a speedo so I could continue swimming with it on. While the Birdlocked is a good chastity device, it's nowhere near descreat enough for me--and it's impossible to stay clean with it on. A few months later, I found Mature Metal and started poking around. After bugging my friend a little bit, he bought it for me under condition I would pay him back with two split-payments over a month or two--and damn was it a phenomenal choice. I've tried on 4 different chastity devices and this is by far the best by many many AUs, and I mean it. I purchased a Jailbird with the following measurements: Oval gap-3/8" | Length-1 3/4" | Ring Size-1 1/2" | Cage Diameter-1 1/8" | Security Screw.

Why did I give it 4 stars? The ONLY reason I didn't give it 5 stars is that it is SO close to being the most perfect chastity cage in existence. I am able to swim with a padded speedo and get away with it--relatively so. I have to stick my butt out so my cage gets pulled lightly between my legs when walking so no one can see.

I think that in order for this to be the highest tier chastity cage ever, that they would have to redesign the locking mechanism--or add a third option. If they managed to make the locking mechanism happen within the actual ring that goes around the penis and shaft--it would make it 100% invisible in even the tightest of undies. The ONLY thing that I have to worry about when people are walking around me is the locking thing jutting out ever-so-slightly, but when you wearing tight undies and pants like me--it's pretty noticeable if the cage twists even a little bit.

In conclusion: If you're looking for an amazingly comfortable chastity cage that's near invisible in tight clothing--and invisible in regular clothing, a cage that--when fitted properly--will force your erection down one or two notches, a cage that looks absolutely beautiful, a cage that allows you to pee standing up, a cage that's as easy to clean as a naked penis, and a cage that's perfect for 24/7/365/lifetime use: The Jailbird is your man.

When mistress and I decided on male chastity, I began researching the subject. I discovered a few facts fairly quickly: 1) most men who have had plastic devices have been dissatisfied with them, 2) the adjustable "one size fits most" idea just doesn't work, and 3) cleanliness was always an issue with these devices.

Reading blogs led me to Mature Metal. When I saw the Jailbird, I knew this was exactly what I was looking for. I have owned mine for a month or so now, and it is truly amazing. It fits perfect, looks great, the open design allows me to breathe, and the light weight surgical stainless steel construction means cleanliness is no problem. I found myself wearing mine almost constantly right from day one. I opted for two different sized base rings and the security screw in lieu of a heavy, bulky padlock; mistress holds the keys.

What was even more amazing was the great support I got from Mistress MM and William. They patiently returned my calls and emails and did everything they could to make sure I got good advice. They really care about customer satisfaction. They are very responsive and trustworthy.

If you decide on a Jailbird, order the sizing rings, wear them for awhile to make sure the fit is right, and follow the sizing instructions to the letter before you place your order. This will minimize, or as in my case, eliminate adjustment issues.

I looked at a lot of chastity devices and I believe the Jailbird is the best hand built custom sized device, made with the best materials, bar none. You will not be buying a generic device; this is your device made just for you. That is what makes this great product worth the price. As other reviewers have said: "You get what you pay for".

Thanks to MM and all their help, this is one Happy Subby Hubby who looks forward to being Locked for Life.
