Reusable Nonstick Construction. Made from food grade silicone and natural glass fibers, this reusable baking mat is a better oven liner than parchment paper when baking or roasting. A Baking Staple. Use it to line cookie sheets and cake pans for easy release without extra oil or butter, and you can also use it for cooling candy and chocolate, or for piping frostings. Healthier Cooking Kit. For savory cooking, use this sheet for steaming meats and vegetables, wrapping tamales and splatter-free microwaving. Versatile Size. The liners can be trimmed to fit smaller ovens or cut any shape to fit for your oven or baking pans. Each measures 60 * 40cm. Keep Your Oven Clean. By placing it on the bottom of your oven, the non stick durable sheet protects oven from spills and splatters. No more scrubbing to remove baked-on residue, your oven will stay clean with every use.
