Made from premium aluminum oxide paper, these self-adhesive sheets offer lasting performance and compatibility with most sanding discs! Self-adhesive backing is easy to affix to your sanding disc. These 12" sheets comes in your choice of 60, 80, 100, or 120 grit.
I could not find these locally. Search popped up ROCKLER. good price, quick delivery and they work perfectly on my Delta sander. The adhesive makes them easy to apply and it has held for a month of use on the first disk. My usage has been almost daily. I use them to sand aluminum mostly. The grit is holding up fine.
