Approximately 26cm aluminum alloy Bottom Round Pan Plus, a lightweight and easy-to-handle cooking utensil. - Brand: Hirata - Model Name: Bottom Round Pan Plus I purchased this from Shop Channel before. I thought it might be a bit small for my household, so I've kept it stored at home without using it. It's new and unused, but the box has a dent, so I will repackage it in a different box for shipping. Although it is unused, it has been in someone's possession and stored at home, so please refrain from purchasing if you are sensitive to such things. m(__)m
