NMINT official Web definition is this:

Cards in Near Mint (NM) condition show minimal to no wear from shuffling, play, or handling and can have a nearly unmarked surface, crisp corners, and unblemished edges outside of a few minimal flaws. A Near Mint card may have a tiny edge nick or a tiny scratch or two, but overall look nearly unplayed with no major defects or flaws.

NMINT cards are not Perfect, they are "new" because they are unplayed but if you want absolutely perfect cards you should buy only PSA 10 cards.
