UltraFlex Softback Sanding Sponge. Size 114mm x 140mm x 47mm (4½' x 5½' x 3/16').
Don’t work like a dog sanding anymore! Use softback sanding sponges! They fit on standard palm sanders, are very flexible, easy to clean (rinse with water), and last a LONG time. The Fine Sanding Sponge is more abrasive and ideal for distressing.
