This is our original southern steel bottle, inspired by Japan's old coin design. The interior is lacquered, and while the lacquer may wear off with use, it transforms into a steel bottle that resists rust due to the minerals found in tap water, including calcium. This characteristic allows it to supplement iron and aid in preventing anemia.Additionally, when boiling water in the iron bottle, it removes chlorine, resulting in tap water with a milder taste. This enhancement makes drinks such as Japanese tea and coffee even more delicious.While it is suitable for direct fire use, please be cautious as the handle can become quite hot. Use it with care to avoid burns. The durability of Iron Products ensures they make excellent gifts for various occasions, including celebrations, Father's Day, and Mother's Day.
