Soft silicone cock ring set with electrical wire. These flat rings are each uni polar. The black part inside is conductive. To obtain shock therapy, you must use both rings together or replace one of the rings with an adhesive gel pad. The cable has a 2.5 mm jack plug which fits into our 3 different power box units ref Ri 7850 Ri 7880 and Ri 7890. Make sure to use enough contact gel to create the best contact with the skin.
