This nail file is made of wood, with a straight shape, and is ideal for shaping and caring for natural nails. It is effectively used to correct imperfections on acrylic or gel nails. It features two sides with different grit levels, specifically 100 and 180 grits, meaning one side is coarser and the other finer. This allows you to prepare your nails before applying products such as acrylics or gels. Its slim shape also makes it suitable for pedicures.
