What is nail filer?

A nail filer is a tool used for shaping and smoothing the edges of nails. It is often made of metal, glass, or emery, and is available in a variety of shapes and sizes. The rough surface of the file is used to gently and gradually file down the edges of the nail until they are smooth and free of rough or jagged edges. Nail filers can also be used to buff and polish the surface of the nail to create a smooth and shiny finish. It is a basic beauty tool used by people of all genders to maintain healthy and neat looking nails.
