The Big Horn 5” Foam Hand Sanding Block Set features two hook and loop blocks that will be an excellent addition to your sanding arsenal. Ideally used to sand those hard-to-reach areas where an orbital sander cannot reach, softening edges, and other detail sanding applications. Block edges are slightly angled inwards to help get into corners, sidewalls, cabinets, and trim.  Can be used with new abrasives and old abrasives that no longer give the full sanding power when used with an orbital sander. These sanding blocks will take full advantage and get the most out of new and old abrasives. Constructed of polyurethane foam for flexibility and a comfortable grip for easier sanding. Equipped with hook and loop system to change between abrasives easily and quickly.
