These oak / cherry bowls are size XL, and fit these biconvex stones with room to spare. I think they are Oak, but the pink hue points to Cherry. They have been treated with Monkey Wax and given 3 weeks to cure. You can see the process of refurbishing them here:

One of the lids has a small chip, as does one of the bowls (probably from the same event). A name is written on the underside in pencil, and can be removed with a hi-polymer eraser.
There are 181 black and 180 biconvex white pieces, about 8mm thick and made of high-quality Japanese glass.
