Powell Peralta Classic BLEM decks:

• Cosmetic defects include, but are not limited to minor scratching, paint chipping, tape marks, fingerprints, paint smudges, out-of-register inks, etc
• Each deck was manufactured in the same way as their first quality counterpart
• Each deck has a minor cosmetic defect and could not be offered as first quality
• Decks are clearly stamped BLEM between truck holes

Some feel that a BLEM deck could have more collectible value than it's first quality version. Much like a mis-stamped coin, stamp or other mis-marked collectible since less of them are being made available.
