This insert will hold both the base game and the Monster Box of Monsters expansion all within the main box. The storage solution is composed of one main tray with three removable trays for resources. It will also hold premium sleeved cards. NOTE: In order to hold all of the cards within the one box, the insert was designed to allow the cards to be stored on their side. Thus, the height of the insert is of an appropriate height and will not allow the lid to close 100%. This is illustrated by the attached pictures. That said, the insert is quite sturdy and will support the lid - allowing the stacking of games on top. ALSO the insert does not come with the foam dividers - just the four trays. (Game not included)
