Despite their similar names, these products are markedly different. Pokemon booster boxes include only booster packs, offering a lower cost per pack than buying individual packs. Booster boxes are geared towards collectors who already have a deck and want to pull rarer cards for it.
Collection boxes include a significantly higher number of cards than booster boxes and come with pre-built decks. Players who buy collection boxes can play right away with their pre-built decks. These boxes also include unique promotional cards and accessories that can’t be found with booster packs.
