Jail Bird



Punishment Pin 1

SKU: 116 Category: Tag:


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.

WOW What a difference!

After having spent 4 years on and off in a CB 6000 and dealing with the frustration of having a device that never felt really comfortable we made the decision to move to a custom metal device. I spent considerable time researching for the right company to put my faith in and WOW I’m glad I teamed up with Mature Metal.

My journey started with reading everything on their website and in particular how important it is to take very careful measurements. I ordered the sizing rings and spent about 2 weeks trying different sizes in all stages of limpness (LOL). I thought I was confident of the sizes but still had some questions and reached out to Mistress MM by email. I was pleasantly surprised with how fast she responded and we had a dialog of several messages. I still had a couple of reservations about a couple of issues and reached out to her by phone. She answered the call and was extremely friendly and very helpful in resolving my final concerns. After our consultation I placed my order and waited anxiously for my new device to arrive.

My beautiful new device arrived about 3 ½ weeks ago and my first reaction was WOW! The craftsmanship was spectacular and it looked like a beautiful piece of jewelry! Very fitting for locking up the family jewels (ha-ha). We now refer to it as my second wedding ring! I was so happy when I tried it on because it felt so comfortable. I made the comment to my wife that it feels like I could wear it forever. She said “Good” (oops).

We are now into our 4th week of continued use and the experience has been amazing. I wore it for 12 days straight on the initial lockup. For a new device this is simply unexpected! I can say that taking the time to measure correctly and consult with Mistress MM was well worth it.

During this time I was able to direct my focus totally on her learning many new ways to please her and giving her much satisfaction orally. On the 13th day she decided she wanted the real thing and she removed the device and instructed me to take a little blue pill which I did immediately. Continuing my focus on her we enjoyed about 45 minutes of foreplay and then she instructed me to put on some numbing cream and a condom. She then proceeded to enjoy an hour of focusing on herself without the possibility of me having an orgasm ruining her pleasure. Then after an extended period of cuddling and the numbing cream wearing off she proceeded to give me a ruined orgasm and locked me back up. Today after another 11 days of lockup without any comfort issues she removed it again this morning and we had another amazing intimate experience ending with another ruined orgasm for me and being locked up again.

This beautiful device has transformed our marriage bringing us much closer together. Since it is so comfortable and suitable for extended ware we now have the delight of making it a permanent lifestyle. It has given both of us the opportunity for more discussion on our needs and wants and how our relationship will grow with my enhanced focus on her. I’m finding myself constantly looking for more ways to make her happier around the house as well as in the bedroom.

She is so delighted she informed me that my initial time without orgasm will be 2 months! I’m looking forward to seeing our relationship blossom as well as how explosive I expect my next orgasm the end of March.

I am very thankful to Mistress MM and her dedicated husband for all the help, support and crafting such a beautiful piece of jewelry. I would recommend Mature Metal to anyone serious about embracing this lifestyle that will truly transform your relationship for the better.

It's been over a month since my lockup began, with only 1 day out so far for a very fierce edging and teasing session, which did not include any sort of finish. My wife absolutely loves the power she has and how she can keep me perpetually hot for her, so much that my scheduled release in February is now pushed back until July, which may turn into an entire year if things continue as they are. I'm still completely comfortable with no chaffing. So far, so good! I'll post an update in July.

Bettter than Expected

I've been ordering cheap metal devices for a couple of years trying to find the perfect size but they were all just a little off. Never could wear one for more than a few days and tended to slip out or have to adjust from being pinched. Not so with the Jailbird. As soon as I got it I put it on and went for a walk. I barely could tell it was there. Wearing it for 4 days and still on with the perfect mix of security and comfort so I can't pull myself out or slip a ball out unintentionally which use to happen all the time with the cheap things. Oh and this is much lighter to with no crappy weld joints to rub your skin. Thank you for delivering a wonderful product

In for the long haul

My wife surprised me with the Jailbird about a week ago. We had been using an off the shelf Chinese cage off and on for the past year with the longest stretch being 3 weeks at a time. Before she presented me with my gift, she had me randomly choose a number between 1 and 6. 4 was the magic number, and unbeknownst to me, that would be how many times in the next year that I will be released. Those 4 dates were also randomly chosen, so my next release is more than 2 months away, with the next being over 5 months from that date. Now onto the device itself... build quality is excellent, by far more comfortable than the Chinese model, as I almost forget that I'm locked up. Upon first seeing it, I thought "No way will I ever got" as it is only 2 inches long and an inch and an eighth inside. My old device was 2 1/2 inch by 1 3/8. It fits wonderful and hugs everything ever so snug.

Just took delivery of my jailbird and what can I say other than wow, the build quality is brilliant and the attention to detail is second to non.
I went for the double base ring and double locking so definitely no escape and the added bonus of a clunking padlock for that little reminder that your no longer in control. Thank you mature metal for such a nice cage.

Eight Months

It has been eight months since I received my Jailbird and have been locked in it continuously except for playtime releases. It is so comfortable that I rarely know that I am wearing it. The quality is great and it looks as good as it did the day it arrived. Cleaning is simple with the cage on which means it does not need to be removed which is great for long lock ups. Correct sizing is important and following Mature Metals advice that the cage should fit like a glove. I wasted money on multiple cheap uncomfortable cages, so glad I made the purchase!

A++++ Received the Jailbird on 6/29 and been wearing it since. Been released 3 times for overnight/play. Waited until now to give a review because I wanted to test it out. Great craftsmanship! It exceeds all my expectations. Above all it's very comfortable to wear long term and easy to clean without removal for a true 24/7 fit. I wish I would have made this purchase a long time ago! My advice buy the rings and measure 10,000 times. When I was trying to find the correct ring for my fit I would wear it a couple of days even to bed until I had it narrowed down. Thanks again!

I have purchased and used various "plastic" devices over nearly 18 years with varied success. I had heard for awhile that getting a metal CB was better so I researched and choose MM. I got my JailBird a couple months ago and immedialty I discovered the advantages and will never go back to a plastic style. First and foremost - I knew the size I needed and MM was able to make it to fit like a glove. I have never gotten a fit this good EVER. The quality is amazing. This is the REAL DEAL!!! The steel is heavy duty, polished smooth and perfectly crafted. I personally got the security screw which eliminates all these different style locking mechanisms into something small and relatively easy to use. I even had them add an extra hole for a separate lock if my key holder desires. With this fit I can easily wear 24/7 and I can do all my normal activities. This Jailbird has a very high level of security so that there is no chance of getting out for me ( there is no other screw driver that will fit this without harming the screw) I also love the feel of the solid steel weight of the jailbird, enough to know it's there but never an issue or hurtful. Plasics are lighter but bulkier - this one is far less bulky and easier to wear. I am extremely happy and recommend to anyone. I wouldn't use any other company, MM service has been fantastic and wouldn't look elsewhere. The money is WORTH IT!!!

I thought I would come back and do a followup review and found my original review from back in March 2014! Hard to believe I've been locked in my Jail Bird for over 4 years now! My wife only unlocks me when she wants to play with my penis and once a week to shave. Otherwise it has only come off for doctor visits and for flying. I am still just as happy with my Jail Bird as I was when we first got it and still believe it is the best chastity cage out there.

by Thom on Mature Metal

Wow, this device is so comfortable, fits perfect and looks really cool. I have been working out and other things I couldn’t dream of doing with my CB6000s. I would never NEED to take it off and can go as long as my wife decides to keep me locked in chastity. If you can afford, don’t spend his one more second in a plastic torture device.
