Thank you for viewing. This is a baking mold from the Matfer EXOGLASS series, made in France from heat-resistant reinforced plastic. It's extremely durable, doesn't chip, is lightweight, and has excellent sharpness. This is a set of three sizes: 40, 55, and 70. - Brand: Matfer - Sizes: 40, 55, 70 - Country of Manufacture: France I may have used it once, but I haven't used it since. I'm offering it for sale, hoping someone who likes it will use it.
