The Red and Black Neon Wand is the the latest device which creates an electrical discharge across the surface of the skin. The electricity produces sensation over a broad range from pleasurably warm tingling to a more intense focused sensation that some find painful. The level sensation created by the wand can be controlled both by a multi-level intenisity dial on the wand itself and also by which electrode you choose to use. The Neon Kit comes with 4 different glass attachments: Electrode comb, Mushroom tube, 90 degree Probe, and Tongue Tube. The kit color refers to the color of the light glowing in the glass electrodes. Can be used up to 25-30 minutes at a time.
