From 2001. I opened three boxes at different times.

Box: 24 packs of 6 cards + 1 binder-offer card. "Plasma" chase cards P01-P12 are inserted at the rate of 1:4 packs. Expect 1.92 base sets (72) per box if collation were perfect.

All boxes produced 2 base sets minus six singles, with no extras. Each also provided the expected 6 Plasma cards.

Base cards and inserts have an "Edition 1" logo on the fronts. "Prelease" chase cards PR01-PR12 were distributed in boxes of Powerpuff Girls Series 2, and are different from the 12 inserts found in the Dexter packs.
