Rather cheap quality
I am hung with erect 12 cm and this cage is way to big. It is made for big cocks. It delivers a nice amount of pain and i can't masturbate with it on.
Urethral Sound for Mystim Pubic Enemy No 1 Chastity Cage
The Urethral Sound for Mystim Pubic Enemy No 1 Chastity Cage is easy to fit into the cb and easily inserted into the urethra. It fixes your cock completely and gives you a very controlled feeling of the cock while in the cage. Very good idea and toy.
A penis cage, or chastity cage, is a bondage accessory that can imprison the penis and sometimes the testicles, preventing any erection, penetration or masturbation. The most famous penis cage is the CB6000, in a plastic or metal version. A penis sleeve, also called a penis sheath, helps to maintain erections, stimulates your partner, and increases the size of the penis.
