The Cloneboy Cast Your Own Dildo and Vibrating Dildo kits contain all the necessary items to make a silicone rubber copy of a penis - either yours or your partners! The Cloneboy uses a medically tested moulding material made from natural algae, and contains no plaster that can irritate the skin. Easy to use, you can clone the penis of your choice in a few simple steps! To ensure perfect results every time, the Cloneboy comes with a lasso cock ring to help you maintain an erection during the moulding process. The kit has a 3 minute mould setting time, and includes an added stimulation sleeve that you can choose to use with either your new creation, or your own penis!
