The E-Stim System Electro Ring System is a fantastic bipolar electrode set that is available in a range of sizes from 30mm to 65mm in diameter. Using two of the ElectroRings and one of the Accessory Pack, you can create a sturdy bipolar electrode that sits around both the testicles and shaft of the penis.

I have designed this clip-in-place silicone insulator to enable stimmers to isolate the top half of any Electro Ring to better target nerve groups such as the superficial and deep perineal nerves.

Check out my article on why using insulators not only makes sense but can really enhance your chances of achieving hands-free orgasms while using e-stim equipment - Electrosex Penis Play Guide For Hands-Free Orgasms.

This is a universal insulator that has been designed to insulate half of the largest Electro Ring, the 65mm diameter one. It can be used on the smaller rings if you trim it to the desired length using a pair of scissors. It has been designed with convenient cut points along its length; in this way, you can tailor the amount of insulation you prefer.

Made from body-safe platinum-cured silicone from Smooth-On Dragon Skin™ 20, an expensive but very safe material used in sex toy manufacturing and prosthetics.

I have had to buy a vacuum de-gassing machine and a pressure vessel in order to make these insulators bubble-free.
