Sanding Sponge

These small, strangely "chunky" black sponges can be used for both dry and wet sanding. They are better suited to fine finishing (i.e. smoothing out an edge after coarser sand paper has taken out the burrs). Daifuku likes them because they save wear and tear on the fingers for surfaces where you want to sand both sides at once: the sanding sponge gives you more to hold onto than a folded piece of sandpaper.
