This too is a 3M product, marked P220 in a burgundy ink on the back side of the grey plastic film in reversed letters about 3/8" high so you read it from its cutting face.. And in characters about 1/8" high between repeats of that, LASTS 15X LONGER LN3 +3 safety symbols in 1/4" circles FOLD. ROLL. SHAPE. one for ear muffs,glasses,respirator On a cardboard core, 4.5" wide, wound diameter 2.5", medium grey color, a bit lighter than a Kodak 18% card, overall. It was the only roll on the shelf so I've no clue what other grits it might be available in. Fairly thin, I'd guess and it doesn't say, that there's 10 feet of it on the roll. I don't keep receipts but ISTR it was about a tenner for the roll. Has a piece of pale chartrues masking 3/4" tape 2" long binding the end of the roll, but I expect that would be any color 3M has a surplus of. And that describes everything I can see with the roll on the tray beside my keyboard. I do not now recall if it had a protective overwrap when it was sitting on the shelf. Probably because it would have had a UPC barcode on the wrapper. Like you, I would break hands putting the money in them if I could find it in finer grades. 600 would the cats meow, and 1200 would make this junk mahogany I'm playing with into wood porn. The way this stuff cuts, I'd guess you could go from a 150 on the RO sander, to this stuff on a small black of flat wood, skip the 320 & go to 600, then 1200 for a mirror finish. I always air hose the surface to dislodge the dust from the wood pores, then try to wipe on enough finish to fill the pores. Done right, it rolls in the light like a hunk of tiger eye, my favorite stone for a bolo style necktie. This time starting with a coat of teak oil, kept wet for about 20-25 minutes (can says 30 but its too hard to wipe at 30 minutes) then wiped dry with a couple big gobs of Scots paper towels, leaves a dull but quite penetrating & surface hardening foundation for a glossy wipeon, give that a day to cure, then start wiping on minwax gloss polyurethane, about a coat a day with a light rub of 0000 steel wool for traction for the next coat, 2 coats sometimes but that makes a long day for me. Done right, just the lid takes about 10 days, 5 on each face. I may even try laying on the last coat with an air brush. I made a kitchen table top for a junk "Bakers Rack" that came with a veneered and warped hunk of OSB for a top, out of sweet gum 15+ years ago, and it still looks good, air brushed it all the way. Laid it flat so I could get it wet but no runs. As a learning experience it was good but tedious as I was doing it on the open but roofed back porch & had to clean the dust nibs off before re-coating it again the next day. Now I have a heated & AC'd garage that didn't exist then. And fewer dust nibs as I have a 20" box fan with a hepa filter to keep the air in there fairly clean, gets turned off long enough to change the filter when I can't see a light thru it, running for about 5 years now, pretty good for a $20 box fan IMO. It actually blows toward the table saw top, which is also used for a work table by tossing a sheet of tool box drawer liner rubber about 1/8" thick down on it.
