Sensation Wheel

The Wartenberg wheel was developed by a neurologist in the 1930’s for systematically evaluating nerve responses (sensitivity) by rolling it across the skin.  It is a rolling pin wheel of sharp little points that aren’t sharp enough to puncture the skin unless excessive pressure is applied.  It’s a great sensation toy and an exciting addition when used with a violet wand. It comes with a sheath for safe storage.  We doubt that Dr. Wartenberg could have imagined that after becoming an antiquated medical instrument, his wheel would see a resurgence in popularity as a kinky toy!
