This baking pan set features an ingenious diamond texture on the base, which enhances its non-stick properties and ensures even and quick heat flow to the cookies, resulting in uniformly baked cookies without any overcooked or undercooked parts. It is made of premium extra-thick material, constructed from heavy-gauge carbon steel that is 57% thicker than ordinary ones. These durable oven trays offer stability, even heat distribution, and long-lasting durability. They can resist temperatures up to 450℉. This exclusive set includes 3 non-stick cookie sheets in sizes 13''x9'', 15''x10'', and 17.5''x12''. The small one is ideal for baking cookies, pastries, and lasagna; the medium size is perfect for jelly rolls; and the large one suits baking chicken and vegetables, etc. It is a healthier baking choice. With a Whitford-reinforced coating for exceptional release, the two-layer coating is chemical-free, containing no PFOA, BPA, or PTFE, making it safe to use. Additionally, its smooth non-stick surface, with 34% silicon content, ensures easy cleaning and protects against scratching, staining, and corrosion. A baking pan set is not just a practical baking tool but also an affordable table art. Excellent kitchen utensils should combine quality and aesthetics. Color: Silver.
