This storage system will hold the base game and the following expansions: 3 is a Magic Number, Atlanteans, Why Can't we be Friends, and the recently released Aztecs expansion. It will also house premium sleeved cards. Note: in order to accomplish this, you will need to use your Aztecs box to hold an insert designed to hold all of the non-faction cards. The storage system comes with (7) trays. In addition to the tray that fits into Aztecs, the system comes with another base tray for the main game box and (6) additional and removable trays. These removable trays will hold game components.
