The Japanese TENGA Soft Tube Cup is designed to give user total control over the desirable tightness. The outer surface is made with a softer plastic material to give you more control over the tightening sensation. The lotion reservoir and 70 gripping nubs make this cup the ultimate masturbator. These reversible nubs in the chamber enable smooth entry and they provide a superb sense of adhesion as they cling gratuitously to your penis when you withdraw from the cup. This Super Size Cup is designed for the male with a larger then average member.
