Our organizer for Path of Civilization is designed to hold sleeved cards. To that end, we have replaced the tech card trays with our own. This requires you to use the stickers on our trays. We only require one of the stickers and suggest putting them below the card slot of the designated location. It also comes with removable and individual player trays to distribute at game start. All of the other resource trays are also removable for quick and easy startup.
