Insert compatible with Teotihuacan, including the Late Preclassic Period, Shadow of Xitle , and Expansion Period expansions.. The design provides both efficient storage and improved game play. The trays can be utilised during the game, and they greatly aid set-up and clear-away times. The rules and boards act as a lid on top of the trays. The insert is a revised design of our original FS-TEO insert, this new version having space for the Expansion Period expansion.
