Until you use these sandpaper rolls, you won't appreciate the savings and convenience of being able to simply cut what you need for each application. I make my own sanding blocks in various sizes and these rolls save me money. The adhesive is good, the abrasive is good, and the storage and convenience top it off. I know, bubbled on the sandpaper. lol. But I use a ton of it and used to buy it from Lowes but the weekend warriors must not have appreciated it and preferred a sheet or two at a time so stopped carrying it around. Now I have a source again.
