Dice Box/Tray - "There's something in there"
The box rumbles. What sound like bones clack inside, the chains rattle and strain to keep the lid on. What's inside? Dice, obviously. Or you could use this as terrain or a boss fight or monster reveal if you just got a big ol' monster mini you want to hype up
Anyway, it's a pair of felt-lined boxes, one acts as a cup and the other a rolling tray.
Chains are bolted to one side of the tray and harness the cup by clipping onto rings on the other side.
