Keep him supremely locked into submission with this extreme chastity cage by choosing one of the three graduated rings to fit over the penis and testicles, then fitting the cage over the shaft. You can choose if you want him to wear the removable cum-thru urethral plug, the detachable anal hook with stimulator, and detachable ball clamp. Each ring has a soft rubber sleeve at the hinge, to avoid pinching and for added comfort. This device secures with a flat head screwdriver. This versatile toy can also be used without the cage. Just secure the top of the ring with one of our brass locks, and this device turns into a cock ring that you can hook your accessories to!
