This Card Management System for the basic plain old Settler's of Catan, holds all the Resource decks (vertically) between the (horizontal) Development deck, and the discard pile. If you want to hold all your cards for a game of Cities and Knights, then a second one of these should do the trick. If you want to hold all the cards for Traders and Barbarians... then you'll have to wait. I haven't even managed to understand those rules yet let alone find some one to play them with.
Cards are not included, and I recommend printing in White Strong and Flexible, unless you want the pretty colours.
