A buff is a special nail file, presented in the shape of a parallelepiped, each face of which has a different abrasiveness . The buff is most often used for grinding and polishing extended and natural nails.
Unlike a regular file, a buff, as a rule, is less abrasive, so it has a gentler effect on the nail plate to give it the necessary smoothness.
