3M™ Softback Sanding Sponges set in Medium (120 - 180 grit), Fine (320 - 400 grit), SuperFine (500 - 600 grit), MicroFine (1200 - 1500 grit) and UltraFine (800 - 1000 grit) grits. This is a set of full sized pads. Each pad measures 4-1/2 inches x 5-1/2 inches. Aluminum oxide is waterproof-bonded to the sponge material yielding a flexible, yet firm pad. These pads work especially well for shaping unfired dry metal clay. They are very good for smoothing flat surfaces and rounding corners. The pads easily polish high spots leaving the recesses dark.
