Note:  Insert designed for game with external box dimensions of 29.6 x 29.6 x 13.4 cm.

Insert compatible with Mansions of Madness 2nd Edition®, and Beyond the Threshold®, Streets of Arkham®, Sanctum of Twilight®, and Horrific Journeys® expansions. The design provides both efficient storage and improved game play. The trays can be utilised during the game, and they greatly aid set-up and clear-away times.

The insert is arranged in three layers with the room tiles stacked in the top right corner.

The larger room tile and rules are placed on top of the insert trays acting as a lid. The game can be stored vertically, and transported easily as it fully fills the game box.
