Enjoy this unique Rolling Head Cup from Tenga! The neck extends and curves so you can feel custom pressure and shape with each stroke. Hit that spot exactly how you like it! Insertion is easy and pleasurable with the smooth pad that helps keeps an air-tight seal and keeps lubricant from spilling out. The insides are already pre-lubricated, so it is ready to go as soon as you open it. Easily taken anywhere, this small, lightweight device is also quiet, discreet and doesn’t require batteries. The suction-cup function can be controlled by applying pressure to the top of the device to adjust air-pressure. After use, simply dispose of the device in a waste bin.
