The straight-shaped file from Staleks is the perfect choice to shape your natural nails or correct imperfections in acrylic or gel. With two sides and differing grit hardness, its use is flexible and adapts to your needs. The grit can be selected according to the stage of nail care: as the grits increase, the texture becomes finer, and the reverse is true for smaller grits, which offer a coarser and rougher texture.
