Sturdy box and lid. A nice size for a base for 3D houses or coffins (!) (or other small scenes with miniature lights, when you need a place to hide wires).
Or flip the lid around as a shorter base, and use the larger box as a shadowbox, as shown in one of the small photos below (with a Gnarly Tree, Mini Black Wrought Iron Fence and a coffin from the Tiny Little Coffin Boxes - Decayed Collage Sheet).
Approx. 8" x 5-1⁄2" x 2" deep. Large enough to put metal feet under.
This box is also included in the Cemetery Add-On Kit; see all the other kit components available to buy separately.
