Note these are unipolar electrodes so you must use two of them or pair with another unipolar accessory to complete the circuit. Connect using the hole in the bottom rubber ring with any 2mm pin leadwire. These fall in-between the small and medium sizes of our other cupping sets (they require no suction gun with the twist top).
Best used on a mostly flat surface or with a bit of water-soluble or adhesive gel to form a good seal for the suction function.
