This Wartenberg pinwheel has 7 small wheels covered in pointed spines. A favourite for bondage games, Wartenberg pinwheels are used to provide gentle or powerful stimulation to the epidermis and the nerve endings near the surface of your skin. The sensation created depends on the pressure applied to the pinwheel, so it can produce anything from a gentle pricking to a sharp pain.
This device is generally used with your sub blindfolded, to amplify the sensations they feel. The spines should only brush the skin and should never pierce the epidermis or dermis.
