The paper nail file with a straight shape is the perfect tool for shaping natural nails and repairing imperfections in acrylic or gel nails. With a grit of 100/180, it features two sides to meet different needs: the coarser side (100) is ideal for more heavy-duty work, while the finer side (180) provides a perfect finish. It is useful for preparing nails before applying acrylic or gel, ensuring flawless results.
