Twist it, pump it, roll it - the flexible folds at the midsection of Tenga's Rolling Head Cup open you to an exciting array of stimuli that deliver special attention to the most sensitive area, the head! Inside the cup is textured with soft and sensational nubs and ridges, to generate complex and satisfying stimulation. The textured chambers also act as valves that create a virtual vacuum, allowing for suction to be controlled by placing your finger over the vent at the top of the toy. And thanks to the clever lubrication ring, your playtime will stay lusciously wet throughout. This toy is disposable and designed for single use, but may sustain another session or two if used with care!
