The Donegal Straight File is designed to provide precise shaping for natural nails and to correct imperfections in acrylic or gel. With its straight shape, it is versatile and easy to use, ideal for both everyday and professional use. It features 2 sides with different grit hardness, allowing you to customize its use according to your needs. The larger the grits, the finer the texture, providing a smoother finish, while the smaller grits offer a coarser and rougher feel.
