The Betty Crocker Bake'n Fill 4 Piece Bake Set is a durable and versatile set of cake pans made of aluminum with a non-stick surface coating. The round-shaped pans come in varying sizes with diameters and depths in order to make the finished cake. Betty Crocker has a long standing tradition of quality products. The pans appear unused. I'm listing them as pre-owned due to not having the recipe book. The instructions are printed on the box.
