A nail polish buffer is a tool used to smooth and shine the surface of the nails. It typically has multiple sides with varying levels of abrasiveness. The buffer helps to remove ridges and imperfections, giving the nails a polished look.
Sanding files, also known as nail files or emery boards, are used to shape and smooth the edges of the nails. They come in different grits, with lower numbers indicating coarser surfaces for shaping and higher numbers for finer surfaces for smoothing.
