Tuckboxes I made using http://tuckbox.gameupdates.com/
for the Development and Resource cards in the base game plus 5-6 player extension.
I made these for my personal use and thought others might find them useful. All resource cards for the base game and extension go in one box. Similarly, All development cards go in one box, and the box tells you which cards to remove if you are playing with 3-4 players.
