The new CB3000 is the ultimate in male chastity! Both adjustable and extremely secure, this device will keep you--or your partner--from achieving a full erection or masturbating, all while letting you view the penis through the clear device. Now combining the cage design of the CB3000 and the ring design of the CB6000 to form the ultimate lock! Three comfortable, flat-designed interlocking rings connect to the cage with a locking pin resulting in a chastity device that is lightweight, durable, and extremely comfortable. Also featuring a contoured shape, holes for ventilation, and an opening for urination, the device can be worn with the included plastic lock to avoid setting off metal detectors.
