There is 1 small and 1 large ring in this set. They are unipolar, ideal for sending the currents up and down the shaft. They are flatter and a bit wider than the other rings we have available and preferred by many of our clients to all others. Connect with standard 2mm pins so no adapters needed.
The larger band is 3/4 inch wide with a 2 inch diameter (unstretched).
The smaller band is 2/5 inch with a 1.5 inch diameter.
They are made of silicone to retain body heat, and stretchy.
