Thank you for viewing. Royal Queen Casserole Inner diameter: Approximately 18cm Depth: Approximately 8cm Can be used for water baths and cold baths when set with 2-quart and 3-quart pots, and can also be used as a lid. ◼︎Used a few times, so there is a feeling of use such as scratches. ◼︎There is a scratch of about 1mm on the back (photo ④), but I think it will not be a problem for use. Please check the condition in the photos before purchasing.
