This storage system is composed of four trays and will hold sleeved cards. (Note the spell cards are fit for penny sleeves as that was all that I was able to find at the time). One tray holds the element card "bank" - separating the "2" and "3" level elements. Another tray is used to hold the element, madness and curse cards for set-up. A third tray holds the various tokens while the fourth holds the character / grimoire cards along with the spell cards.
