I just checked out the website for industrial abrasives and here's some info: 50 pack of wet/dry silicon carbide (black)$16.00 that's for any grit 1000 and up - to 2000 if you want that high. Also, 100 pack of 600 grit wet/dry SC $27.00 up to 2000 grit also. I haven't bought sandpaper in along time so maybe I'm off base with the prices. I was just hoping that this can help. Mike 2Lane
