Here's where it all started, the original Pocket Monsters. The corners are not perfect, but the seal is tight, and inside there will be two Pokemon cards, and a packet of apple-flavored gum. I would not recommend trying the gum, it might be expired, but the cards should be new. I cannot tell if they will be blue-backed or green-backed; most probably they are green.
