This insert is composed of four trays and is part of our new pre-assembled plastic insert line. It will store premium sleeved cards and is designed for the base game and Hall of Heroes and Fields of Fame expansions. The base resource tokens are stored inside the black bag and stored as seen in the picture. NOTE: in order to also store the expansions you will need to use either of the expansion boxes to hold the new player boards and expansion manuals. If you don't own the expansions you can fit everything into the main box with room to spare. ALSO, this insert will hold the token upgrades provided by Top Shelf Gamer. (The insert does not come with them and they must be purchased separately). They are a great upgrade to your Terraforming Mars game and can be purchased here.
