This modular organizer holds Memoir 44 terrain tiles. The attached pictures show tile storage for:
Base Game 2x - Green
Eastern Front 2x - White
Mediterranean Theater 2x - Yellow
Pacific Theater 2x - Brown
Terrain Pack 1x - Gray
Winter Wars 1x - Black
I color coded my tiles to make it easier to find specific tiles. There's also room (with a bit of lid lift) for storage of a game board and 2 sets of card holders under the tiles.
