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.

Customizing your Jail Bird

The punishment pin  and the security screws options are available for this item.  The Jailbird must be 1 1/4″ inside diameter or larger and a length of at least 1 1/2″ for the punishment pin option to fit.

Extra rings are priced at $80 each.  Any Jailbird over 2″ can have the cage made with three rings. 3″ cages can have a total of four rings.  Depending on the length of the cage, the anti pull out may be able to be added.  If you have any questions about these options, please feel free to email us.  Please know that a proper size lock should sit sideways.

This changes everything

My Jailbird arrived in the mail on October 13 at 3:00. At 3:20 I had put it on. It has not been off yet. My previous experience has been with the CB series....2000, 3000, 6000S. I had no idea what a dramatic difference there would be going with a custom fit Jailbird. The comfort level is total, no burning, no rubbing raw. I'm not waking up 4 times a night with the feeling that my balls are being torn off. The Jailbird is so comfortable that I forget I'm wearing it during the day. It allows me to experience my Chastity as a unique kind of pleasure, not as a torture. Thank you Mature Metal......I think you've made me an addict.

Plastic is for toys -- metal is for men!

After experiences with three plastic devices that ranged from disappointing to dismal, my Wife/Keyholder and I finally agreed that we should stop "cheaping out" on a piece of hardware that represented such an important and basic part of our lives, and get serious.The Jailbird is serious. And you have to be serious about it if you're going to get it. Get the sizing rings and use them. Take your measurements as instructed. And understand that this is a custom made product that is going to go around a temperamental and squishy bit of male anatomy. It might take some work and trial and error to get it right.But oh sweet Goddess when you get it right, the Jailbird is IT! Locked up safe and secure!Don't make the mistakes I made, the mistakes that made me waste so much time and money on plastic devices. Don't be scared by the cold sleek look of stainless steel, don't imagine that it MUST be less comfortable against your private parts than plastic. It is much MORE comfortable. And much easier to keep yourself clean without unlocking.A MM Jailbird is quite simply IT for male chastity. If you need to be locked up, this is the device that will do it!

Happy to be locked in a Mature Metal device

We received our first Jail Bird chastity device from Mature Metal December 2014 and I was able to wear it quite comfortably immediately for several days at a time without any discomfort. Wearing this device 24/7 for weeks at a time is now the norm, removing it only for short periods of time with permission from my mistress. If you are contemplating your first chastity device, do not follow the online advice to start out with a CB600 device. You will waste your time and money. The material and build quality of the Jail Bird device is nothing short of excellent, and it is so easy to wear with little to no adjustment time. Wearing this device for work and play under most any type of clothing is also not an issue. To ensure a good fit, I strongly recommend that you read the online advice on how to size the device correctly the first time, and also be sure to consult with William and Mistress MM. I am very happy to be locked in my Jail Bird chastity device. Our relationship and ability to communicate has improved in so many ways since wearing this device. Thank you Mature Metal for such a high quality jewel like device and for the great customer service.

Finally, one that works

We have tried different cages and that all had to be taken off regularly, after 6-8 days usually because them rubbing the back of my ball sac raw. They would have to be off from a week to 10 days to allow healing. Your company was sour last home. We decided to put the jailbird on for a few day, take it off for a day or two, and then repeat the process lengthening the time it was on until teh cnaffing problem went away. It has worked and I have now been continually locked for 42 days with no problem. I am concerned because my wife said we have tried over 20 devices over the years and and a month of continuous chastity for each one tried will finally let me know what I asked for years ago and never achieved. This 42 days is the longest ever and it will be 2017 before she lets me out she says. You make a quality product and I need fo face my fate now.

Jailbird excellent for husband's small penis management

My hubby is a grower, not a shower; flaccid about 1.5 in, erect about 5.5.

I tried other devices (cb6000, cb6000s )on him but after a couple of days the pinching and hygiene became issues. The Jailbird eliminates those problems, now having him locked for over two weeks now.

It is such a very nice looking device/jewllery I may take him to Gunnison Beach to show it off latter this month!!

Thanks Mature Metal for resolving his long term masturbation addiction

Jail Bird

We’ve tried plastic and metal cages before but decided we wanted a custom made cage I could wear permanently. We are so pleased we chose the Jail Bird. The look, the comfort, the security, the hygiene, in fact everything about the Jail Bird surpasses our expectations. If, like me, you don’t get the sizing right first time and need an adjustment, their customer service is second to none as well.
I couldn’t wish for a better chastity device to be locked in permanently, Thank you Mistress MM and William for making this possible.

only way for a tiny dick

I never thought a tiny docked fag could find a devise tat would stay on, less then 1" when soft, only a few inches when hard. Finally a way to keep it locked and secure. Thank you, its the best.
Check out this Alphas twitter @DetyroiktDoug for my small locked up dick. (7/14/15)

Awesome chastity device

I have tried a number of different chastity devices from the cheapest to more expensive silicon. I can honestly say that the custom fit Jail Bird beats every other chastity device I have tried. Not only is it so comfortable that its feels like its not even on but the price is just right. The sizing rings they have really help in getting just the right fit. The Jailbird is a great 24/7 chastity device. Get it you won't be disappointed.

Will do wonders for your life. 24/7

My husband had brought the idea to me a few years ago and we like others purchased some kind of plastic device and what a waste of money . Finally my husband researched the Mature metal and showed me all the info and since then it has been nothing but a pleasure to deal with the great people who own the company but also the extreme knowledge they have of the product they sell. This device is so much more then a lock , it has changed our marriage and our lives. It's comfort for him is unbelievable and its unnoticeable under any gym attire as well as the fact that it's secure . It's a work of art ! Pull the trigger and invest in this bit of jewelry that gives your relationship an energy that cannot be described but is felt time and time again.. The mental change for him also is noticeable in minutes of clicking the lock . Thank you again Mistress Mm and William .

Are you sick of restless nights? Tired of cheap plastic cages breaking on you and making you uncomfortable? Fed up with having to remove your device every three days for cleaning? Get this device. Stop thinking about it. Stop wondering about it. Just do it! You'll be glad you did. This device is so comfortable I can barely feel it. This is VERY important. Without a comfortable device, you will not be able to focus on anything and it will impact your sleep. This device is hygienic and easy to clean. This is also VERY important. Can you really feel like your in chastity if you have to remove it every few days? Of course not! Can you really feel like you're in chastity if you're in a plastic device? Absolutely not! Look around online for blogs about the Jailbird. Figure out your size (smaller is always better IMHO) and get locked up! I agree with ALL of the posts on this review board. THANK YOU MATURE METAL!!!
