A quick insert to hold sleeved cards. It does add some height to the box, but it does support sleeved cards and holds the expansion as well. I put the dice and tokens used every game in the token tray, and the other cubes/scenario items in the center well of the card tray.
The card tray does require supports since I had to remove the side walls to accommodate sleeves.
