INSCUP 3 is an automatic masturbator that features intelligent built-in thrusting and 360° circular contraction functions. It is equipped with a powerful telescopic motor and an electronic air pump, providing users with dual stimulation through thrusting and contraction for the ultimate pleasure experience. The INSCUP 3's soft sleeve, made of high-quality TPE material, aims to deliver maximum realism and comfort. The sleeve is easy to detach and reinstall. Magnets are attached to the bottom of the sleeve and inside the casing. When you place the sleeve back into the casing, the magnetic force will automatically install the sleeve properly in the casing. This avoids complicated procedures and allows you to quickly resume your enjoyment. The penis sleeve has a drainage hole at the bottom, making it convenient for cleaning. For added comfort, always use a generous amount of lubricant on your penis. After use, clean the toy with lukewarm water and a toy cleaner, and store it in the OTOUCH pouch after natural dry.
