These Nest™ Bake stackable round cake tins are made from heavy-gauge carbon steel with a dual-layer, non-toxic, non-stick coating free from PTFE, PFAS, PFOA, Lead, and Cadmium. Easy-pull handles make them safe to handle with oven gloves, and the stackable design allows airflow and prevents scratches when stored. Ideal for baking, they are hand wash only, oven safe up to 232°C, and compatible with other selected Nest™ Bake items.
