Scotch 26120CP-P-G Sandpaper Sheet, 11 in L, 9 in W, Medium, 120 Grit, Aluminum Oxide Abrasive, Paper Backing Purple

3M Advanced sandpaper is now better than ever, thanks to our new No-Slip Grip™ backing that is applied to the back of our 3M pro-grade sandpaper. No-Slip Grip™ backing provides longer sheet life 7X longer than conventional sandpaper. For the better sanding results, sand with the grain of the wood and work through a sequence of grits, from coarse to ultra fine, skipping no more than one grit between sandpaper.
