I purchased this two years ago and used it about three times. Since my family has downsized, I've been storing it at home. I'm now using a convenient 18cm smaller one. Compatible with both IH and gas cooktops. Just put in the ingredients, bring to a boil, and then let it simmer. Saves time and reduces energy costs (compatible with induction cookers). Retail price: 16,287 yen I used it on an IH cooktop, so there's not much burning or scratching. It's still in good condition, so I'm selling it. I'm also listing it on other sites, so I may remove it. Thank you for your understanding.
