The UpLac nail file is made from paper material and has a straight shape, offering the ability to shape natural nails. It is ideal for correcting imperfections on acrylic or gel nails. It features two sides with different grit hardness, where the larger the grits, the finer the texture. Conversely, as the grits decrease, the coarser and rougher it becomes. Its slim shape also makes it suitable for pedicures.
