This All Black butt plug is beautifully smooth and has a delicious widening in the middle that will give you tremendous anal stimulation! Definitely recommended for the user looking for a firm but surprising toy. 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.
