The Japanese are masters of engineering, and with their ingenuity they've brought jacking to a whole new level! Enter the Tenga Flip Air. It's re-useable, luxurious, compact and light. You experience a different suction and sensation every time you use it. You simply press the button to set the silicone elastomer material to the desired shape and release. The mold holds place. The effect is similar to sliding into a soft slit with a strong vacuum. When you press the button again, the mold returns to its original shape. The Black model is 7" in length and can accommodate up to 6" in girth.
