This combination tray-and-tuckbox system keeps your commodity and progress cards organized both during play and in the box.

[Similar trays for resource cards can be found under the main Settlers of Catan page. If you wish, you could replace the development cards with "Defender of Catan" cards. Or just keep the development card tray closed and place the "Defender of Catan" cards on top of the closed development card tray during play.]

Cut along solid gray lines. As with standard origami notation, dashed lines indicate valley folds, while dotted-dashed lines indicate mountain folds. Apply adhesive to solid gray areas. With these guidelines, assembly should be self-explanatory.
