The paper nail file in a square shape is ideal for buffing the natural nail plate as well as your acrylic nails. With a hardness of 80/120, it has two sides that offer different textures, allowing you to choose the appropriate one according to your needs. The higher grit value (120) means a finer texture, perfect for finishing, while the lower (80) provides a coarser surface for more demanding tasks. It is an essential tool for your nail care.
