Microwave Heat Plate Super easy grilling, just heat it up in the microwave. The heating element on the plate reacts to electromagnetic waves (microwaves) and generates heat. Since you don't use fire, children and the elderly can cook safely and securely. With the sliding lid, you can also steam cook as you like. You don't have to worry about dirtying the inside of the microwave. Unused, but stored by an amateur, so please refrain from purchasing if you are sensitive to this. ■ Plate Material: Porcelain Size: 24 x 15.5 cm Height: 3.5 cm Weight: 850g ■ Lid Material: Polypropylene (Heat resistance 140 degrees Celsius Cold resistance -20 degrees Celsius) Size: 25 x 16 cm Height: 3.5 cm ■ Accessories Instruction manual
