Everyone needs a 9" x 13" cake pan. Professional pastry chefs and bakeries bake on aluminum for consistently perfect results. You can do the same with our commercial-quality Naturals® Bakeware. Made of pure aluminum, these premium pans will never rust or warp, and they produce evenly browned baked goods every time. Comes with a lid for added functionality by sealing in freshness and making transport simple. Lid snaps around edges to keep contents fresh. When pressed down properly on the ends the lid will snap over the rim of the pan to fit. The lid lightly clicks into place, it is more of a loose fit on all pans. Proudly made in the USA.
