Its comfortable grip allows you to accurately wipe down surfaces to keep you from accidentally erasing important information. Compact size fits on most accessory trays to ensure it always stays within quick reach. Or, store the eraser in the included magnetic caddy. Dry-erase board eraser is optimized for use on glass dry-erase boards.
