USD 12 for a sheet of sand paper?
No thank you.
And they don't even mention the size of the sheet or further specifications then just the grid size.

that sounds like emery cloth. its substrate is like a textile. Its durable and not as cheap.

you can find norton specs on their website from the part number. Its considered a premium brand, meaning there is some secret to control of grit sizes and adhesive. i noticed cheap sand paper sucks
Cheap emery cloth loses its abrasive fast and also disintegrates too easily and tears ugly. The cheap brand leaves you with a pile of abrasive after only moderate work (dirty)
typically if you hear emery despite the fact that its not a name for a rock, it means cloth
however, emery cloth is not suitable for lapping or flattening, which is why you want to stock both.
and its strong enough that its very dangerous on a lathe, potentially, don't wrap it around your fingers!!!
I never saw actual emery abrasive on paper either, if it was truely on paper then tis a super boutique product and I expect the price to be very high
for a ring, if its deformable, it means you can do polishing that is light on the hands by putting emery cloth over something like a thin piece of deformable foam, to get some conformal action. if you have to do 50 rings, having a big peice you can drag them over while avoiding loading is handy
keep in mind otto is a supplier for gold smith and stuff like that. the man hour that goes into making a jewlery piece is very expensive compared to basically any materials, except for platinium lol
and good emery can last longer, and also its something that can tackle nasty burrs on the side of objects alot better, but its not THAT good that it will replace a f ile
