I bought this two years ago and used it about three times. I've been storing it at home since my family downsized. I'm now using a more convenient 18cm smaller one. Compatible with both IH and gas stoves. Just put in the ingredients and bring to a boil, then leave it. Saves time and reduces utility costs (compatible with induction cookers). Retail price: 16,287 yen I used it on an IH stove, so there's not much burning or scratching. It's still clean and can be used for a long time. I'm also listing it on other sites, so please understand that I may delete it suddenly. Thank you.
