This nail file is made of paper material and features an ergonomic crescent shape, which provides precision during use. It has two sides with different grit levels, 80 and 100 grits, meaning one side is coarser and the other finer, allowing the appropriate adjustment for each step of the filing process. Ideal for shaping the natural nail and preparing it before applying acrylic or gel, this file is essential for every professional as well as for personal use.
