An essential in any Dom/me's kit, the Wartenburg wheel is a medical device used in bedrooms and dungeons as a sensation tool. This classically-styled pinwheel is made from stainless steel, with a ridged handle and single wheel with a row of sharp spikes evenly spaced around its perimeter. As the wheel is rolled across bare skin, the spikes' needle-point tips deliver an exciting prickle of sensation. Experiment with using it on different parts of the body, applying different levels of pressure, warming or cooling the Wartenburg wheel before using, or by pairing with a compatible electrostim device.

The wheel comes with a reusable plastic sheath that protects the device from bumps (and protects you from unexpected pokes when you reach into the toy box).
