Welcome to the new E-Stim Systems ElectroRings
Others may offer simple cock rings, we have created not just a single ring but a system of rings that can function as cock rings but can also take your electro cock play experience to the next dimension with a more 'electrifying' chastity like device, using the E-System ElectroRing System.
Each ring has been created to work with our heavy duty 4mm connectors, perfectly designed for use with our low profile connectors. We don't even force you to choose which side you connect the cable to - the ring socket connections are double sided.
We have the widest range of sizes from 30mm to 65mm (internal diameter) all in our durable satin finish.
Use a paper or fabric tape measure to measure. This is the circumference or girth that you need. Use the sizing table to determine the ring size you need.
