Insert compatible with Gloomhaven: Jaws of the Lion. The design provides both efficient storage and improved game play. Many of the trays can be used during the game, and they greatly aid set-up and clear-away times. The boards and rule books act as a lid on top of the trays.

This product consists of a flat-pack of 5 Evacore sheets. The trays require assembly, which is quick and fun, using ordinary PVA glue. Detailed instructions are included in the package.
