The Ergo Ball Stretcher Kit from Mister B is an ergonomically designed stretcher that hugs your ball sack as well as the base of your cock. Unlike other ball stretchers on the market these are soft and stretchy, and intended for more long term wear. The kit includes two sizes. Wear either long, short or both for a tight fit. Use with any lube. Since 1994, Mister B has been producing high quality erotic articles that have their origins in the gay fetish market, allowing the user to develop their sexuality.
