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.

The cage for Jailbird can be built with more than just the two rings. Please see the final image on the gallery below for an example. 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.

Jailbird excellent for husband's small penis management

Aug 21, 2015 by Pleased Manager

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

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.

Awesome chastity device

Jun 28, 2015 by John

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!!!

best device I have ever had

Apr 05, 2015 by josh

I have recently bought the jailbird with an extra cage ring and I am completely satisfied I have owned a cb600 and a birdlocked both have fell drastically short on quality and comfort when it comes to long term wear thanks again mature metal

Incredibly comfortable

Mar 30, 2015 by DS

My Mistress made wear the Jailbird the minute it arrived and I have been wearing it ever since, albeit for more than a week. It is so comfortable you actually forget you are wearing it. The quality and workmanship is perfect, and truly well crafted.
Having experimented with several plastic CB devices, all of which I could not wear for longer than 2 days, plus struggling to keep my penis clean for Mistress, the Jailbird's open design makes staying clean easy. It is truly a practical, and permanent chastity device, in fact its so comfortable you will want to wear it...
Getting the sizing right is critical and its well worth getting the sizing rings first before you order, really helps, plus the team at MM is awesome and extremely helpful and experienced, in answering all your questions.
The entire experience, obtaining advice, ordering, and receiving this excellent product is top class. My Mistress and I cannot thank the team at MM enough for their excellent product and making long term or even permanent chastity a reality for us. 5 STAR Plus

If at first you don't succeed try again

Mar 29, 2015 by No more chubby for stubby

I bought a jailbird and wore it off and on for a while, then it was decided that it would be more permanent and that's when I noticed there was something that just didn't seem right. It seemed I could almost achieve a full erection as it would pull on my balls and pull away from my body, so after a couple of phone calls and numerous emails to mature metal, I found the base ring and the cage length needed to be made smaller. I sent in my device and got it back very quickly with the changes and wow what a difference it made. I just wanted to say their customer service is second to none and would recommend this company to anyone who is in to chastity, as with me they will do everything to give you the best product possible, thank again for everything any I am extremely happy

What can I say that hasn't already been said? The first one I had made, I was cocky and though I could go an inch shorter. Boy was I wrong! This device has no give and no movement at all, so too short was not good. Nice thing is that the resale value is rather high so I sold it for a very small loss and ordered another with more appropriate measurements. Unbelievable the difference it made. If you have questions they answer truly and give great advice. Ultimately it is up to you to take the advice or not. I learned to take the advice. When you get the right size this device does exactly what it's meant to do. I love mine and haven't been out of it since it arrived.
