The wooden nail file in a straight shape is ideal for shaping natural nails and correcting imperfections in acrylic or gel nails. This particular file offers an excellent solution for professional and home use, as it is designed to meet the needs of every user. With the gradual change in hardness of the grits, you can choose the texture that suits your requirements. The larger the grits, the finer the surface, providing a smooth feel during application. Conversely, with smaller grits, you have more roughness, ideal for initial shaping.
