【Price reduced to 1700 yen from 2000 yen during the Super Mercari Sale!】 Diameter: 20cm, Depth: approximately 10cm The inside appears to be coated, which may make it less likely to burn food. The heat source is unknown. It was stored unopened, but I opened it for the listing. There is an odor due to long-term storage. I wiped it with alcohol for the listing. The box also has an odor, so it will be shipped in a recycled cardboard box. Thank you for viewing. Please also read the profile page.
