This is a card holder for Settlers of Catan. It is meant for cards that are 54mm x 80mm. It has 6 slots which hold the 5 resource cards and the development cards. There is a slope to help keep the cards in the tray, as well as a finger groove to help grab the whole stack when you are done playing! We've loved using this to keep the cards neat during play.  Also check out my holders for the roads, settlements, and cities!
