Abstract

A nail file may comprise a cardboard made of a polymer such as polystyrene (PS), and each of two surfaces of the cardboard has an ethylene-vinyl acetate (EVA) layer which is served as an adhesive to adhere a polyethylene terephthalate (PET) film thereon. Also, each of two PET films has a plurality of grits formed thereon to create a rough surface thus achieving the effect of filing nails. Since the PET film is a material which is an excellent water and moister barrier, the PET film is configured to firmly attach with the cardboard even when the nail file is washed by water.
