Wartenberg Pinwheel With Leather Sheath

The Wartenberg Pinwheel has prickly pins that can be rolled over the skin, creating a tickling and teasing and tingling sensation that many people find incredibly arousing. Invented to test nerve responses for possible damage, the Wartenberg wheel is pointy enough to stimulate wherever it goes, but not sharp enough to puncture skin.
The best way to use me:
Lightly roll over the skin for a unique sensation.
