This Non-Stick Silicone Jelly Roll Baking Mat is a commercial-grade silicone mat that’s specially sized and designed for cooking and baking in a standard jelly roll baking pan. Woven glass fibers sealed inside the baking mat transfer heat evenly, so that jelly rolls, breads, dough, pastries and other baked goods cook to a perfect golden brown, every time. It’s a must-have of cake making and baking tools, and will quickly become a favorite among baking accessories! Holds 15 (2-inch) or 12 (2.5-inch) cookies. Safe to use for freezing foods, too. Non-porous surface eliminates the worry of cross contamination of foods. Dishwasher safe and stores away easily, either laying flat or rolled up. Durable, reusable and naturally non-stick so cleanup is a breeze. Strong and durable, it will outlast thousands of uses at a wide range of temperatures (-40 degrees to 480 degrees Fahrenheit). Reusable and more economical than using parchment paper. Foods release quickly and easily without oiling or greasing the surface - perfect for those watching their calories.
