SANDING BLOCKS: This set includes 2 sanding blocks. The blocks are made of quality yellow polyurethane foam, strong and durable. Each sanding block has an ergonomic shape that is comfortable to hold. At the bottom of the block there is a hook-and-loop base for attaching a sanding disc, which prevents any shifting or rotation. Both blocks measure 12 cm in length, 7.5 cm in width, and 3 cm in height. The hook-and-loop base allows for adding and removing replacement discs. Use this sanding block to attach sandpaper or polishing pads. The hook-and-loop base holds the discs to the sanding sponge. Each block supports discs with a maximum diameter of 12.3 cm. Use the sanding discs on a flat or curved surface. The pads have angled sides to facilitate sanding in grooves and tight areas. ERGONOMIC PAD: The two blocks in this sanding kit are smooth and light in the hand. There are 3 finger slots at the top for better grip and control. The polyurethane foam is flexible and very durable. Apply pressure to any wood surface you are sanding without tiring your hand. The body sanding block also helps dampen vibrations and minimize heat transfer during use. WIDELY USED: Our blocks are ideal for many uses, such as woodworking, furniture recycling, and crafts. Use them for dry or wet sanding. The pads are suitable for all grits. Attach sandpaper to the wood sanding block to sand drywall, plasterboard, wooden fences, and wooden furniture. Attach a polishing disc for automotive work in a body shop. Product color: yellow Delivery quantity: Two pieces
