Pure Copper 5 Go (900ml/30oz) Rice Pot Shinko Metal Japan. With newly developed ceramic-containing fluororesin coating. Instead of a smooth surface like before. The unevenness of the rough ceramic particles changes the way air bubbles appear during boiling. This allows the rice to circulate with many bubbles and cooked evenly and deliciously with even heat. Also rice doesn’t stick to the inside, making it easier to wash. Main body: Pure copper. Lid: Double layered 18-8 stainless stell. Inside: High-strength ceramic sprayed fluororesin processing. Cannot be used in IH, Microwave oven. We do not mark item values lower or mark items as “gifts” in accordance with goverment regulations. International Buyers – Please Note.
