This insert is designed to be compatible with Architects of the West Kingdom, including the Age of Artisans expansion and the Architects 2018 KS Promos pack. 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 rules and boards act as a lid on top of the trays. This product consists of a flat-pack of 4 Evacore sheets. The trays require assembly, which is quick and fun, using ordinary PVA glue. Detailed instructions are included in the package. Note: Insert designed for game with external box dimensions of 23.0 x 23.0 x 6.9cm.
