Assortment of 6 sanding sticks of varying grits: 120/180/240/320/1200/1500. Designed for use on both small and large surfaces thanks to their unique feature: while one is wider and can be used on larger areas, the narrow portion can be used for hard-to-reach areas and small parts. The more aggressive grits are particularly useful for gradually eliminating the most prominent surface defects, while the two finest grits can be used to create an extremely fine and smooth finish, leaving the surface ready for painting. Can be used on a full range of materials including resin, metal, wood and, of course plastic. This abrasive can be used both dry and moistened with water.
