These two lightweight plastic clamps feel very sexy to even wear alone. They do not pinch very tight, making them great for use on the most sensitive private areas. They can stimulate great pleasure if used correctly, or simply be used for positioning without electrical current. The design makes it easy to use with or without other accessories. One set of two clamps works on one circuit/channel, each clamp is unipolar, so use with caution above the waist! It is best to split the channel, pair each clamp with a nearby electrode pad and not send current across the chest.
