Here is a handy little Sanding block for use with sanding discs you have around the shoop. Sanding with the same abrasives is important and these sanding blocks allow you to do just that. These blocks have an ergonomic design that makes them "feel good" in your hand. Using a block eliminates finger marks when sanding. Available in 5" and 6" Vinyl back for Peel and Stick paper as well as H&L (Hook and Loop) for Velcro backed paper. The block is yellow CELLTEC®.
