Electrostatic open-coated surface with space between the grits ensures consistent dust removal, preventing sheet clogging. The tough abrasive grit is resistant to wear, allowing for extended and repeated use. Fully synthetic resin-bonded grit for durability. Highly flexible paper backing allows folding without cracks.
