The FIR Mysterious Vessel (Arita-yaki) is a special magnetic plate that allows you to grill fish and meat in the microwave. It converts the microwave's microwaves into heat, allowing for fragrant cooking without the need for plastic wrap. Benefits of Use: * You can cook fish, meat, vegetables, etc. in a short time, heating them from the core and not losing their flavor. * The far-infrared effect makes the outside crispy and the inside juicy. * Cooking is possible without oil. * Serve directly at the table. Cautions: * Due to the nature of the charcoal material, there may be pinholes (small holes) on the surface. * You need to season it with oil before use. * This is only part of the explanation, so please search for "FIR no Utsuwa" (FIR Vessel) for more details. Thank you for viewing. Dimensions: 15.5 cm x 21 cm
