Thank you for viewing! I've only used it a few times. It's still in good condition, so please consider it! The interior has a fluorine resin coating, making it easy to clean. It comes with a glass lid, allowing you to check the cooking progress. It's compatible with 200V IH and can be used with all heat sources, including gas. The 26cm size is generally suitable for 4-5 people. Please refrain from purchasing if you are overly concerned about scratches or stains, or if you are overly sensitive. Please check the product condition in the photos. D-09 21
