Japanese Jet-Black Spirit · Booster Boxes
Sealed product · price from PriceCharting
A booster box is a sealed case of Jet-Black Spirit Japanese booster packs. Japanese boxes are smaller than English ones — most expansion sets come around 30 packs to a box (each pack about 5 cards), while premium "high-class" sets come in smaller 10-pack boxes. Opening one is the most efficient way to chase the set's SRs, SARs and other high-rarity cards.
Standard contents; exact pack counts can vary by release.
