To be exact, this is not a dice, but a two-barrel three-barrel whiteboard on mahjong. The principle of gravity induction is also used to control the gear switch of the electric fan. Whiteboard-off, one barrel-first gear, two barrels-second gear, three barrels-third gear.

Ha, ha, ha, ha.
Still a dice
It's beautiful
Creativity, praise!
