Easy elegance! Armetale® metal is a unique, non-toxic aluminum-based alloy, that never tarnishes, making it always ready for cooking and entertaining. Hot foods cooked and served in Wilton Armetale® stay hot longer, and cold foods stay cold longer. There is one 7.75” x 9.75” oval-shaped tray and one 6.5” x 9.75” rectangular tray with uniquely embossed rims. Both can be used in toaster oven.
