Magnetic pot: The outer lid has two chips on the handle. Please refer to the photos. A magnetic pot (jisei nabe) is a heat-resistant ceramic pot specifically for microwave ovens, with a special ferrite (magnetic material) baked onto the inside. It converts the microwave's microwaves into 100% far-infrared rays, allowing you to cook food healthily and plumply without losing the nutrients and flavor of the ingredients. This is its biggest feature. Main Features and Benefits: Far-infrared cooking: Less uneven heating, expected to prevent food oxidation and increase nutritional value. Time-saving and healthy: Cooks quickly and allows you to cook with less fat. Safety: Provides peace of mind because microwaves do not directly hit the food.
