This is a card box designed to store the cards from Wingspan. But I did upload the design without the logo so it can be printed with a different logo for a different purpose, or just plain. The card slots are 90mm x 60mm. I do not use sleeves so I am unsure if sleeved cards would fit.

Two boxes fit all bird cards, bonus cards, automa cards, and instruction cards from the base game, European expansion, Asian expansion, and Oceania expansion (but not much more)! A person could fit four of these card boxes inside the base game box on top of the player mats, leaving the space where the bird feeder is stored.

The lid is held on with magnets. I used 4mm x 2mm magnets and the slots in the design are 4.5mm x 2mm. A person could print it and not use magnets. The lid it fairly snug,
