Pokemon 2016 XY#11 Explosive Fighter series booster box (20 packs) (1st Edition). It was only available at the Pokemon Center and a few toy stores in Japan, in June, 2016. The box contains 20 booster packs. Each pack contains 5 random cards. PLEASE NOTE: There are holofoil cards in this series, but they are NOT in every pack. They are randomly inserted. The full set contains a total of 54 cards plus 4 super rares and 1 ultra rare (total of 59 cards in the set). NOTE: You will NOT get the complete set by buying 1 booster box. All contents are completely random and I have no control over which cards that you will receive since the box is sealed. The series has some new Generation 6 characters as well as some of the older Pokemon characters. The booster packs are 1st edition which is only sold for the first few weeks of production (The cards have the "1st Editon" stamp on the bottom corner of the card).
