Made from a highly durable Polycarbonate, the CB2000 is the ultimate mate chastity device - in terms of security and comfort. It consists of two parts: a cock ring and a cage which surrounds the penis. A lockable nylon post holds the cage against the cock ring and when locked in place it is very difficult to remove. Whilst worn, it prevents the victim from achieving a full erection and effectively prevents masturbation. It does however rub and press against the penis, making it difficult for the wearer to forget that he has it on; this in turn can keep the wearer in a state of extended sexual frustration. The design of the device allows it to be worn for extended periods (several weeks or more). Different size cock rings and spacers allow the CB2000 to be fitted to a range of penis sizes.
