This new, improved silicone cup from Tantus is built for comfort and stability--as well as variety. With a smooth and even base, the cup suctions to most flat surfaces (including headboards, showers, and walls) and is compatible with most toys and dildos. Simply remove the bullet in your favorite vibrator and insert the tapered end. No more wobbly, unsteady cups! Best of all, the silicone material is soft and flexible and moves with both the body and the toys used. This accessory is compatible with water-based lubricants.
