Stellar Hard Anodised 32cm Baking Tray. The usual fantastic quality of Stellar Hard Anodised Cookware, now available in a wide range of bakeware too; and these baking trays are no exception! Unlike traditional non-stick, the hard-anodised surface will not peel or flake and will never rust. Even better, the baking trays are metal utensil safe and can even be used on top of the hob (excluding induction) and under the grill so you can have complete freedom and flexibility to put your culinary skills to the test - or just pop something in the oven!
