Insert compatible with Gloomhaven: Jaws of the Lion®. 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 rule books act as a lid on top of the trays.

The trays are arranged in up to four layers. All the trays are in full colour print, and two different colours of foam are used on the different sheets. A new character card tray replaces the tuck boxes that come with the game.

The insert includes trays for storing and organising all of the game components. There is space for all cards to be sleeved with quality sleeves. Every monster type has it's own slot, and all trays include colour icons on the print to show what goes where.
