It's time for another Chinese Mystery Object. If you can guess what this is, please let me know in the comments.
This object is made out of wood, and is reasonably large, about 18 inches in its longest dimension.
Here are a couple of hints: These are still in use, and have a practical function (as opposed to a merely decorative one).
Some of you might already be familiar with these, so I'll use Rosemary's system of turning on Comment Moderation for this post. If your solution is correct, I will withhold it until the end, to allow others a chance to guess.
The answer will be revealed in a few days. Good luck!
