Pinwheel with sharp nails aka Wheel of Pain

The Wheel of Pain is also known as Pinwheel and a favorite toy for fetish play for beginners and die hards alike. The medical name for this device is Wartenberg Pinwheel. The sharp, yet teasing tips give you the option to tickle, tease or, too... as long as the wheel rolls over your partner's skin.
The pinwheel is a medical instrument made of stainless steel and can be sterilized in an autoclave.
The more pens, the less the pain.
