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 punishment pin option 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.

Excellent Craftsmanship and Service

I have had my Jailbird for a few weeks now, and it feels like home. I had previously worn a Holy Trainer Version 2, which was a great product to test this lifestyle choice. The Jailbird is in a league the HT2 will never know.The Mature Metal team's advice during the sizing process was spot-on. I was somewhat fearful of the device being sized too small, but it ended up a perfect fit. I now know the HT2 had way too much space to move.I realize the chastity device's effectiveness lies between our ears in reality, but the Jailbird makes me feel securely locked away, and my wife loves the look much more than the plastic HT2. It was worth every penny.Thank you Mature Metal!

The best

I have had mine on since December 22, 2015 without removing it once. I had been promised to only have to wear it for a month. Now I do not know when I will be released. My wife has decided to keep me in it. It is comfortable but frustrating. It is much better than my previous $700 cage that required a piercing.. If you want the best, this is it. Be careful that chastity is what you really want because this cage is fool proof.

Amazing product

This is a long overdue review. I bought the cage last January and have been wearing it ever since. I've tried the CB6ks, Holy Trainer v2, and a bunch of other cheap Chinese devices. None of them can compare to this device. It was uncomfortable at first because the cage was a little too long. I had it shortened and now it fits like a glove. Small enough to hold it but strong enough to prevent any sort of erection. The cage is very light too. If you're serious about chastity, measure carefully and get this cage, you won't be disappointed.

Making me smaller

Amazing product. Have always had a small penis when not erect, so am wearing your smallest length cage. However I am a a grower and wearing the cage has reduced my erection from almost 7 inches to 3 inches. Best thing of all is that my wife prefers my cock being smaller. She has jealousy issues likes the fact that I am unlikely to show a tiny penis to a new partner.

I've been locked up in plastic devices and decided that i needed to upgrade. I ordered the Jail Bird and all i can say is WOW. Mistress MM was great and the device is outstanding. This has been a wonderful experience from start to now. As i sit here writing this, while locked up in my new Jail Bird, I know that I have the right device to help me reach my goal of 24/7 365.If your serious, Mature Metal is the only company to consider.

I've tried a handful of chastity devices and they all had their issues. As I dug deeper and deeper into the reviews I saw more and more people recommending Mature Metal. I took measurements, sent emails with questions, compared to my old device, and made an order. Yeah, these are more expensive. But you can't beat the custom fit and the build quality is excellent! I'm so glad I made the decision to purchase this from Mature Metal, will definitely recommend. My Goddess says it looks so good she can't see a reason to ever take it off.

It's been overdue for a review, but you know how life is, you get caught up with things, don't really have time for anything.....but anyways I wanted to let people know that Mistress MM really provides quality chastity devices, and I am really grateful and appreciative of their support and advice.....great customer service....And I'm thinking of getting another one for my collectionThank you soooo much !!!!!!!!!!

Superb Customer Service!

This review is for the superb customer service provided my Mistress MM and William. My device had to be returned a few times for adjustments. Mistress MM and William provided quick email response, helpful suggestions to address some burning problems, and worked overtime to get the device back to me. I'm pretty sure that one of them made a special trip to the post office just for me if not two trips. I can not overstate how helpful both of them have been.

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!
