Foodsafe construction: Made from foodgrade carbon steel with a European standard fluorine dragon coating. Nontoxic and 100% harmless for safe food contact. Durable and stable: carbon steel resists twisting and warping, providing longlasting dimensional stability for repeated use. Fast, even heat distribution: The steel body conducts heat quickly and evenly to produce consistent browning and texture across the whole pan. nonstick surface: The fluorocarbon/fluorine dragon coating is 100% nonstick and noncorrosive, making release of baked goods easy and minimizing the need for excess oil or butter. Oven compatibility: Suitable for use in all types of ovens. Multipurpose cutter design: Integrated cutter layout lets you bake uniformly sized brownies and square mini cakes; the pan also functions as a flat baking sheet when you remove the insert. Easy to clean: Removable structure simplifies washing. Hand washing or machine washing is possible, though hand washing is recommended to extend the life of the coating. Use a soft sponge or kitchen brush to remove bakedon food, then dry thoroughly before storage. Practical performance: Durable coating and steel construction ensure repeated nonstick performance and corrosion resistance over time. Use scenarios: 1. Home baking: Bake evenly sized brownies for family gatherings or packed lunches using the integrated cutter for consistent portions. 2. Smallbatch production: Use the pan's removable insert to produce mini square cakes or desserts for bake sales, parties, or catering orders. 3. Versatile oven baking: Remove the cutter insert and use the pan as a standard baking sheet for cookies, roasted vegetables, or reheating. Care tips: Prefer hand washing with a soft sponge to preserve the nonstick coating. Avoid abrasive cleaners or metal scouring pads. Dry completely before storing to prevent moisturerelated damage. What you get: A robust, foodgrade carbon steel brownie pan with a European standard fluorine dragon nonstick coating, designed for consistent baking, easy portioning, and straightforward cleaning.
