Tenga Flip Hole is designed to be the best male masturbator on the market. The Tenga Flip hole is deliberately not a simple artificial vagina – it is better. Filled with silicone ribs; nubs; gates; flaps; and pumps; the Tenga Flip Hole has an astonishing complex inside shape. Every centimeter of it has a particular function. Its flexible casing with buttons allows a total control of the stimuli. Flip Hole is the first masturbator that can open itself completely. For this reason it’s really easy to clean and to always keep it hygienic.
