Based on the original vacuum cup masturbation, the Air-Tech series does not contain an internal sponge, making them hygienic, washable, and suitable for multiple masturbation sessions.

The internal air chambers dynamically increase the suction power of the vacuum suction, which is a popular design feature.

The super tight Strong Cup features thick raised ribs, different textured sections, and an ultra-tight grip for intense, more than satisfying sensations.
