Doc Johnson has designed a fabulously simple, yet highly stimulating masturbation sleeve for every guy out there. Made out of super soft and stretchy ULTRASKYN™, this sleeve will fit just about any guy with ease, up to 7" wide. This masturbator is simply a tube, as the name implies, and it features internal ribs for extra stimulation. Perfect for someone who doesn't want a body part replica stroker. Made from phthalate-free body safe material.
