The metal nail file in a straight shape is the ideal choice for the perfect care of natural nails, as well as for correcting imperfections on acrylic or gel nails. Thanks to its hard material, it offers effective shaping and finishing. Its dual sides provide the flexibility you need, as their hardness varies according to the size of the grits. The larger the grits, the finer and smoother the texture, ideal for the final finish, while the smaller grits ensure a hard and rough feel for initial shaping.
