No grade between the ultracoarse sides and four superfine grits.  Low quality for the price.<br /><br />Bought these on a whim, shined up my nails once and as soon as I touched anything they were scratched again.  Duh, (even healthy) nails are soft.  I guess they could be useful if you clear coat your nails immediately after?
