Fact: This metal pinwheel, known as the Wartenberg Pinwheel, was originally designed by a medical professional to test for nerve damage on the body. Kink enthusiasts have adapted the pinwheel as a sensory play staple. Perfect for all kinds of bondage and dominance scenarios, roll the pinwheel lightly over the skin and create an exhilarating, endorphin-releasing sensation. Weighty and ergonomically shaped, the sharp, spiky wheel rolls smoothly on a slim handle that fits comfortably and securely in hand, allowing for perfect placement and easy maneuvering. It comes sheathed in a sleek black leather case, great for storage and travel.
