TENGA

Tenga (masturbation toy)

Tenga Onacups are a Japanese made brand of artificial vagina (called onacup in Japanese) with multiple models that feature different sensations for the user. It was first released in 2006 in Japan by its founder, Mr. Matsumoto, a former mechanic whose focus was to create a male sex toy with good design that didn't look cheap. By 2007, Tenga had sold over two million onacups and became the most popular male sex toy in Japan.

Tenga Onacups are single-use masturbators that contain molded silicone with lubricant already in the chamber. However, in 2008 Tenga released the Flip Hole, a reusable onacup masturbator with a unique design that "flips" open for cleaning. It is also possible, although non-trivial, to disassemble the disposable onacups and perform appropriate cleaning. Onacups can also be reused several times if one uses a condom to avoid ejaculating inside the chamber. Lubricant should be reapplied to ensure maximum comfort if necessary.
