Wedgie WCW001 Wedgie Premium Cymbal Washer, 7 Pieces Kit, Single Package Drummers have premium cymbal washers made out of a high quality elastomer (rubber). Engineered with 5 touch points to minimize contact with the cymbals, which provides cleaner longer lasting tone. The visible cell wall structure is off-set from one side to the other to flex and respond while still supporting the weight of the cymbal. Wedgie's premium cymbal washers are more durable than the traditional felt variety, which peel apart over time. Patent Pending
