I was at Dollar Tree again, just minding my own business, when I spotted these wooden trays:
According to the company website, they measure 1.75" x 6.75" x 4.875". The oval handle is .5625" tall.
So I thought: dice tray! A wooden dice tray is so much better than using some game box lid. (Just make sure your dice are larger than the openings.)
Or if you prefer another style, they also have the larger Wood Trays with Handles, 7.625" x 5.875" x 2.125". Might be useful for carrying your painting supplies?
I don't know what kind of plywood these trays are made of, but the wood is 'fuzzy' in places, and note the unfinished wood in the handle opening. So you might want to take the time to clean the wood up a bit, or perhaps add paint or stain.
Here in the corner, you can see a glue smear, and a bead of glue along the bottom seam. The wood in the corner is cut unevenly. But then, it only costs a dollar!
