If you have been looking for an affordable, light weight, comfortable yet secure chastity device, look no further. The patriot is built for long term wear, and is designed to be both secure and comfortable. This is my own design that I am manufacturing in my home using a 3D printer. The red tube portion is made of a hard plastic with an inside diameter of 1 3/8" and length of 2 3/4". The blue ring is made of a strong but flexible rubber like plastic. It's inside diameter is 2". This will fit most medium sized males. It will flex enough to get around your testicles for a tight fit, but once it is placed onto the pins, it will not stretch enough to remove your testicles. Some customizing is possible. Please email me prior to buying if you need this item customized. The white portion of the chastity device is also made of hard plastic. The center pin has a hole in it for adding a small padlock.
