Punish your plaything, or even yourself, with a screwed up vice! Shove that scrotum in and see what happens! Five sharp screws line one side of this evil contraption while a crank lowers steel bar, designed to squish the balls against the screws. Remove the screws for a different sensation as the scrotum is trapped between two metal edges. The crank twists down very gradually to allow you to take the pain and pleasure at your own pace. Clean after use with soap and warm water.
