The Straight Paper File is ideal for helping you shape your natural nails as well as correct imperfections in acrylic or gel. Its material is paper, providing a smooth and efficient experience during use. It features two sides with different grit hardness, allowing you to choose the one that best suits your needs. As the grits get larger, its texture becomes finer, perfect for finishing, while when they get smaller, it gathers more roughness for more demanding tasks.
