These are boxes to be used with the map tiles for Mansions of Madness 2nd Edition and dividers for ease of discovery. The dividers are used to find tiles easily and be able to put them back with ease. The dividers included here do have Recurring Nightmares and Suppressed Memories as optional dividers but I don't actually have those expansions as they have been out of print for several years. This means the boxes likely won't be able to fit RN and SM as well. I have also made the boxes quite beefy (3mm walls) so they can stand up on their own despite the weight of all the tiles being flipped back and forth. If you think they'd be fine with thinner walls, just let me know and I can easily update new ones.
The boxes are only made for the currently available 2nd Edition Core box and the following expansions: Beyond the Threshold, Horrific Journeys, Path of the Serpent, Sanctum of Twilight and Streets of Arkham.
One of the pictures shows how the map tile boxes sit in my core box. I have one expansion box with all the monsters minus Star Spawn, Lloigor and Ancient Basilisk. The core box carries those 4 monster figures, map tiles and all other components. The core box lid is lifted by 6cm but I'd rather have that than 3 different boxes.
If someone wants to make the boxes include Recurring Nightmares and Suppressed Memories please let me know how much longer each box needs to be.
