Plastibell
The Plastibell Circumcision Device is a clear plastic ring with a deep groove running circumferentially designed for circumcising infant males. The Plastibell is placed onto the head of the penis during a 10-minute surgical procedure, and the device will fall off within 3 to 7 days. The Plastibell was invented by Hollister Inc in 1950, and first reported on in 1953.
