Box 1 contained cards 1-42 and 127-168 on "Foil Board" (Think Chrome Refractors)
Box 2 contained cards 43-84 and 169-210 on "Lt Fx" (Think Fleer Metal)
Box 3 contained cards 85-126 and 211-252) on "PETG" (Think thicker than average acetate)
The first 126 cards were of veteran players, with one card per "Technology" and cards 127-252 being all rookies limited to 550, meaning each player has 3 different cards in the set. The PETG (or Polyethylene terephthalate glycol-modified) are clear plastic cards that fit into the "acetate" part of my collection. The "Technology" is pretty much wasted on these as only the top portion of the card is clear, and the back containing a bio and stats shows though to the card front. The photos used on the PETG cards look to all be posed studio shots, making my dislike for these cards even greater.
