Mirka's 70x125mm 13H is the smallest hand sanding block in the yellow/black premium range. The sanding block has an ergonomic shape with low profile. The performance is excellent in combination with Mirka’s ABRANET® abrasives. The hand sanding block has an optimized hardness of the backing material. Thanks to its small size the hand sanding block is ideal for smaller surfaces and difficult-to-reach areas.
