These combine multiple delightful sensations. They are unipolar electrodes, Suction is activated simply by pushing down in the center. The genius is the bottom is composed of a circular sponge. When it's mildly damp the electrical sensations spread along through the entire surface rather than just the circular edge of the electrode. You will love them from the moment you try them!

Sold as a set of two.  Connect with pins to a hole in the top. Size: Outer diameter at largest part is 2.2 in. inner diameter of sponge is 1.7 inches.  

May come in blue or gray.
