The TENGA Flip-Hole Male Masturbator is a Japanese innovation in male masturbation.
The Flip-Hole does not attempt to replicate a vagina, but instead aims to give a whole new range of sensations to the user.
Inside the device are a varying pattern of bumps, waves and nodules which allow you to vary the stimulation depending on how you hold it.
In addition, three buttons allow you to apply pressure and suction to the penis in a variety of ways.
The TENGA Flip-Hole is designed for multiple use, but unlike lesser masturbators is very easy to clean. It flips open allowing easy rinsing, and it even incorporates a drying stand in the design.
