Insert compatible with Wingspan, and the European and Oceania expansions. 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.
