"The Grombal protects your cymbals, one of the largest investments in your drum kit. No more searching for washers or felt pads that have slipped off the stands and into your gig bag. The Grombal requires a one time insertion into the mounting hole of the cymbal. The Grombal can also bring old cymbals already suffering from egging or key-holing back to their original mounting and balance. So whether old or new your cymbals will benefit from the Grombal."
