The Tenga Premium series is characterized by being made of better quality elastomer than the previous CUP models, thus providing a more pleasant and soft feeling. Its internal urethane foam is high-end and provides a sensation of thrust at the time of insertion. Inside we find textures that increase the sensations at the moment of friction. The Rolling model is characterized by having a spring-shaped body, which facilitates rotation in all directions, thus providing free movement during masturbation, imitating pelvic movements during penetration. At the tip it has a hole that, when pressed and left covered during penetration, creates a vacuum, thus creating a very pleasant sensation of suction. It comes lubricated with a soft and neutral lubricant that helps penetration to be fluid. This model is intended for single use, since the internal cover is not removable and cannot be cleaned properly. Features: hand masturbator Better quality elastomer than previous CUPs.
