Paper covered on one side with abrasive material (such as sand) glued fast and
used for smoothing and polishing. SAND PAPER 32.5X20CM PKT is used to remove
material from surfaces, either to make them smoother (for example, in painting
and wood finishing), to remove a layer of material (such as old paint), or
sometimes to make the surface rougher (for example, as a preparation for gluing).
