The most recent design from the creators of the famous CB2000 and CB3000. It can be worn for long periods of time and doesn't show under normal clothes. The cage size is just a bit shorter than the CB3000 and the cockrings are made of two separate pieces that lock together when the cage is assembled. In the package you'll find 5 cockrings in different sizes, a set of spacers to adjust the belt to your anatomy, a brass padlock and a set of 5 monouse plastic locks. The plastic locks are numbered so that you can't replace the one you're using with another one!
