The packaging for this grip says it all - Sharper! Tougher! Grippier! This special grip tape pack from Seismic features a special grain that way out-performs the aluminum oxide and silicon carbide variations on the market. This stuff is not just sharper and grippier, but also more durable, heat-resistant, and water-resistant, with outstanding adhesion to decks. Highly recommended. Each pack contains 3 11" x 11" sheets.
