Eighteen packs, exactly half a box, and worth buying only when it undercuts half the going rate for a sealed 36-pack box. That is worth checking rather than assuming, because half boxes exist to hit a lower price point rather than to offer better value per pack. Where the format does well is on a small set, and Chaos Rising qualifies at 86 cards in the main run and 122 in total, so eighteen packs covers real ground instead of sampling. Mega Greninja ex is the set's central card and the reason its sealed product has moved as well as it has. Released 22 May 2026. Confirm any listing is a manufacturer-sealed half box rather than eighteen packs a shop has bundled itself, since the two carry different prices and only one is sealed.
