World Cuisine's paper baking molds are oven-proof and extremely convenient as they eliminate the delicate unmolding process, as well as the transfer and storage of the cakes and pastries. Each mold is freestanding and microwave and oven safe up to 450 degrees F. Each mold is freezer-safe as well. These baking molds have a dark brown paper background accented with gold fleur-de-lys. They are made of pure cellulose calendered paper and are micro-flute corrugated with micro-perforations to eliminate excess humidity. The walls are made of high density pure cellulose flat-calendered paper with micro perforations.
