This is a set of 4, full sized pads measuring 4-1/2 inches x 5-1/2 inches. Aluminum oxide is waterproof-bonded to the sponge material giving a flexible, yet firm pad. Flexible foam backing adapts to unique contours and access hard-to-reach areas
Perfect for use with base metals and silver. To keep them separate, cut the sponges/pads in half or quarters and mark with a marker what clay you used them for to avoid cross contamination.
