Query: Buyer beware!

These are attractive pieces, but please note the warning that came on the package: "This product is not a toy! It is not intended for use by children under 13 years old." As it has nothing to do with the size of these pieces (otherwise they would not be suitable for under 3 years old), the warning may have something to do with other safety concerns -- perhaps something in the paint or stain? The box does not say where the pieces are made. (We're not risking it; we returned them.)
