TENGA Air Cushion Cup is the world's first onacup to combine the use of air pressure with carefully designed texturing. The unique clinging sensation is made possible by the free changing of air pressure in the 24 air cushion chambers. The inner sleeve is pre-lubricated and resides in the cup. There is also a small air hole on top to give you full control of the vacuum sanction.
Onacups are designed for one time use. Use it with a condom if you are planning to reuse.
All TENGAs have lubrication inside. The lubrication consists of: purified water, glycerin, sodium polyacrylate, phenoxy ethanol, and paraben (allergy tested in Japan).
