Thank you for viewing. This is an iron frying pan for making rolled omelets (tamagoyaki). According to the store clerk at the time of purchase, it was manufactured in Niigata, Japan. I bought it several years ago, but I'm selling it because I don't use it. Because it's made of iron, the instructions were to heat the pan well after applying oil, then pour in the egg mixture to prevent sticking. When I made it that way, I was able to make beautiful rolled omelets. Please understand that this is a used item, has been stored by a private individual, and will be shipped as is. Thank you.
