Elastic "O" rings expand enough to allow them to be slid over scrotum (including testicles) and then released at desired point. Ring steadily squeezes shut all arteries supplying either area with blood. Without blood, tail and scrotum dry up and drop off over a period of 10 - 20 days.
Use with Ring Expander sold separately.
Pack of 100 rings.
