The Neon Wand is a popular device line that creates an electrical discharge across the surface of the skin. The electricity produces sensations over a broad range from a pleasurably warm tingling to a more intense focused sensation that some find painful. The level of sensation by the wand can be controlled both by a multi-level intensity dial on the wand itself and also by which electrode you choose to use. The Neon wand kit comes with 4 different glass attachment - Electrode comb Mushroom tube 90 degree Probe Tongue Tube - that will be a thrill to experiment with. 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 Clean before and after each use.
