Fun box to open and the price of around ten dollars is pretty good. Contains 36 packs-the box itself is not sealed and the packs can be opened and searched and resealed fairly easily-so buyer beware. The early boxes (no way of telling) contain some significant error cards and all the boxes may contain rookie cards of Ken Griffey Jr. There is no difference between Hobby or Retail boxes and there are no shortages of these boxes or unopened cases.
