Union Arena — Booster Boxes

A Union Arena booster box is the best way to dive into your favourite anime series in Bandai's crossover trading card game. Each box is a full display of sealed booster packs from a single title, giving collectors a strong shot at the set's parallel and special rarity cards, and giving players a deep pool for building a deck. Booster boxes are ideal for fans of a particular series and make a standout gift for any anime fan.

Boreal Gaming carries Union Arena booster boxes for a wide range of series, from Jujutsu Kaisen, Hunter x Hunter and Demon Slayer to Attack on Titan, Chainsaw Man and Re:ZERO, plus extra volumes as they release. Earlier boxes remain available while supplies last. Browse all of our Union Arena sealed product for packs and starter decks too.

A box of pulls deserves protection. Sleeve your favourite cards in card sleeves, organise your collection in binders and portfolios, and keep your deck safe in a deck box.

Boreal Gaming is Niagara's local game store for Union Arena and anime card games. Shop online for shipping across Canada, or pick up locally and open your box in store. Our team is happy to help you find the series you love.
