This storage system is composed of three trays. Two of these trays are removable and used to store the various tokens used throughout the game. The organizer will hold the cards in premium sleeves. It holds the base game but then is designed to hold whichever expansion set you may be using by storing the main set cards into a separate storage solution. (We offer one here). As pictured, the lid is designed to only partially cover the organizer so as to hold the cards on their side. NOTE: The blue bag for the tokens does not come with the organizer (it was hand crafted by my wife). The slot is designed to hold the tokens in either a thin bag or ziplock bag).
