The soft material quickly adapts to body temperature during use. The Tenga Cup can be used alone, but it doesn't have to be. Couples also enjoy using it for variety in their shared play. The inner material is TPE, the outer shell is made of PE plastic, and the sponge with the lubricant (concealed inside, just after the entrance) is made of PU foam. The cup is designed as a disposable item, which is why it is so lightweight. Multiple uses are not recommended, but it is possible with a condom. DIY enthusiasts can also disassemble the cup, clean it, and reassemble it for further use (with additional lubricant) since the casing is not glued. Masturbators are hygiene products and should only be used by one person. The product operates without electronic components. Disposable item - dispose of the product after use according to the regulations of your local waste disposal service.
