This All Black butt plug gets ever so slightly thicker the deeper it is pushed into your anal which makes penetration even more intense. For the slightly more extreme lover, this toy is definitely recommended! Lubricants based on both water and silicone can be used. It is important to clean the butt plug properly after use. For easier insertion and cleaning of the butt plug, we recommend Kiotos lubricants and toy cleaner, among others. Each toy is individually tightly wrapped in a clear plastic protective case. Contains no plasticizers and is cadmium and lead free.
