This is an iron owl. I used it twice and then didn't dry it, so it has a little rust. I'd like to sell it to someone who understands. There is no box, so I will send it in simple packaging. I borrowed the brand name from Nambu Tekki. It's a cute, round iron egg. You just put the iron egg in the kettle when boiling water or in the pot when cooking! The water becomes milder, so please try it in your daily tea, coffee, and miso soup. Iron is released when you put it in when boiling water. It's perfect for iron supplementation because you can repeatedly consume it in your daily meals. It is recommended for those who are anemic, as well as pregnant and breastfeeding women, children during their growth period, and those on a diet. After the water boils, take it out and dry it.
