Printed on the cloth of each file is the grit as well as a color that corresponds with the grit. This special set contains 3 different thicknesses (2mm, 3mm, 5mm) and 11 different grits (120, 240, 400, 800, 1000, 2000, 4000, 6000, 8000, 10000) for a total of 33pcs. Each piece is approximately 35mm x 20mm. Each piece is already cut for the perfect size for use, and includes 1 of every thickness and grit. This is a limited time product.
