This insert is designed to be compatible with Concordia. The trays have sufficient space for either the Salsa expansion (as shown) or Britannia/Germania board, but not both at the same time. There is space for all cards to be sleeved.
The design provides both efficient storage and improved game play. Many of the trays can be utilised during the game, and they greatly aid set-up and clear-away times. The boards and rules act as a lid on top of the trays.
Note: with the Salsa expansion inside the forum board makes the box lid rise 3mm when closed, so it does not close fully flush with the base.
Insert features:
Two player pieces trays, with player boards as lids
One tray for resources and money
One tray for salt resource and city tiles
Two trays for cards and forums
The sheets also include "legs" which can be added to the trays. If you don't have either of the expansions. These raise the trays up to fill the space that would have been taken by the additional board.
