A well-designed mineral nail file with an optimal grit level is intended for precise and safe treatment of natural and artificial nails. The curved shape ensures comfortable use in the cuticle area and when working on complex filing lines, allowing full control over each step of the procedure. Two working surfaces with 100/100 grit are suitable for intensive filing and shape correction. The hard abrasive is effective for artificial nails, reducing length and preparing the surface before extensions, while remaining gentle enough not to damage the nail plate.
