- Highest-quality materials: Made from BPA-free silicone reinforced with glass fiber for a soft, durable, non‑wrinkling, non‑fading surface. Rated to withstand temperatures up to 250°C / 480°F and reusable over 30,000 times. - Kit contents and sizes: Two half-sheet mats (16-5/8" x 11") and one quarter-sheet mat (11.5" x 8.5"). Mats are 0.75 mm thick and designed to fit standard half-size baking pans (18" x 13") and quarter-size pans (13" x 9"). - Built-in guides for consistent results: The half-sheet mats include 15 small circles and 5 large circles to help size cookies and macarons precisely. Small circles support cookies up to 2.5" and the larger circles accommodate pizzas from 5" to 9". - Non-stick, low-fat cooking: The silicone non-stick surface removes the need for cooking sprays, butter, grease, or extra oil, so you can bake and roast with less added fat and fewer calories. - Easy cleanup and reusable: Replace single-use parchment with these washable mats. Most residue wipes off with warm soapy water—no scrubbing or soaking required—so you spend less time cleaning and more time cooking. - Versatile performance: Use for baking cookies, macarons, and pie crusts; roasting vegetables and crispy potatoes; making biscuit buns; or baking personal pizzas that slide off the mat cleanly. The mats also handle sticky confections like toffee and caramel without sticking. Use scenarios: 1) Macarons: Place batter onto the small-circled mat for uniform shells and consistent baking without piping templates or parchment. 2) Homemade mini pizzas: Shape dough on the large circles (5"–9") so pizzas cook evenly and transfer off the tray without tearing. 3) Roasted vegetables and sticky candies: Roast carrots and potatoes directly on the mat for even browning and easy cleanup; bake toffee or caramel without sticky residue. Why you need this set: - Saves money and waste by replacing parchment and single-use liners. - Ensures repeatable, professional-looking results with size guides. - Makes low-fat cooking and easy cleanup practical for everyday use.
