Tenga Men's Masturbation Toys
First released in 2006, Tenga is a Japanese manufacturer of innovative masturbation sleeves for men. Originally specializing in one-time up masturbation toys (onacup), Tenga has gone on to design the re-usable Tenga Flip Hole in a variety of textures. Unlike other men's toys, the Tenga Flip Hole can flip open for easy cleaning and features multiple textures within each sleeve. Additionally, the tightness of the Tenga Flip hole can be altered by applying manual pressure to the exterior of the sleeve. Tenga also makes the incredibly popular (and cute!) Tenga Egg. Available as a single egg or as a carton of 6, each egg features a different texture.
