Price is per sheet.
This is the sandpaper I use to blend all filing, grinding, or 400 sandpaper marks together into a pristine metal canvas. Each particle on the micron paper is exactly the same, so it quickly gives you a consistent finish. I never attach one component to the next without first bringing them to a green micron finish. You can always polish to a higher shine later or leave it with the lovely, satiny finish the green micron paper makes.
