How to put on

We advise using some lube first inside the ring, on your balls and also your penis.

Push one ball through the ring, followed by the other. When both of your balls are through the ring you push your penis (on top) through the ring , pull your penis completely through the ring. Thread the strap on the cage and attach the cage to the ring placing your penis inside. Put the strap around the ring, pull it as tight as you like and simply put the chosen hole of the belt over the nylon pin. Done!
