Spectra Electrode Gel is a salt-free, hypoallergenic gel that helps increase conductivity between your skin and the electric current experienced during electro-sex play. This results in a more intense and pleasurable experience, and a smoother more consistent electro-sensation. Apply liberally to the skin where you are to be electrically stimulated. This gel is compatible with adhesive pads, clamps, and other electro-sex accessories. Size: 8.5 oz tube.
