Union Arena sealed

Coming soon

Nothing listed in Union Arena sealed yet. The newest cards are in new arrivals.

Sealed UNION ARENA booster boxes from Bandai in Japanese print. Every box holds 16 packs of 8 cards. The set code on the box is the quickest way to tell releases apart: Re:ZERO Vol.2 is EX17BT, while the first Re:ZERO box is a different set, UA40BT. UNION ARENA English sets come out separately with their own codes, and every card in these boxes is printed in Japanese.
