This listing is for a set of melamine plastic microwave cookware baking dishes. One is marked as a Rubbermaid 2 qt / 1.9 L ring bundt / angel food cake pan. The post in the center has some scratches.  The other has the Anchor Hocking logo and the numbers PM447-TI 486 3 and "Made in U.S.A."   Both are marked as handling temps below 400F / 204C. The bundt pan says microwave, conventional, or convection oven use, but not the broiler or stovetop.  They can be stored nested together.
