No one who appreciates Toys should be without a WARTENBERG PINWHEEL! Sometimes referred to as a NEUROLOGICAL PINWHEEL, NEURO-WHEEL or simply a PINWHEEL. Sensations from this handy Toy range from a SCINTILLATINGLY SENSUAL prickle to a WICKLEDLY SHARP pin-pricks, depending on how much pressure is applied. Made of High Quality Stainless Steel, these Pinwheels (which measure approxinatekly 7 Inches long) possess grooved handles and a rolling head of EXTREMELY SHARP POINTS. Each comes in a vinyl case.
