It is ideal for decks with 50 double-sleeved cards in standard inner sleeves or 60 single sleeved cards. Due to translucent materials and smart positioning of the closing flaps, the top card is fully visible from the outside without opening the box. The innovative secure click-lock mechanism protects your deck while still allowing easy access. The Bastion consists of 2 symmetrical parts that easily convert into a card pile and discard pile holder. Also includes a write-on sticker!
