This is the famous brush that clips on to most headshells. At 1.5 grams total weight and made in USA it sweeps surface dust out of the path of your stylus. The pivot is adjustable to suit your tonearm. This item is new old stock so the metal is a bit tarnished and may contain tiny rust spots. This item is intended for older phonographs that are generally equipped with older type ceramic cartridges, not newer turntables.
