These Chinese porcelain trays have a convex center so water will run to the edge. The surface is stain- resistant. They are available in three sizes.
Small - 7-1⁄2" x 11"
Medium - 11" x 15"
Large - 13" x 17"
Customer notes: The porcelain coating may occasionally chip on the rim, but this will not affect the working surface for colour mixing.
