Made in Japan, Marushin Copper Omelet Pan, Kansai Style (Rectangular with Ears), 13.5cm. I purchased this from Amazon for around 5000 yen and have used it with care, but unfortunately, I can no longer use it due to a move and not having a gas stove. I am selling it. Because it is made of copper, the color will inevitably change like this. I have used it about 10 times. The size was easy to use and just right. I was able to make very beautiful and delicious rolled omelets. Please secure the wooden handle yourself with something like a nail. Please understand that this item has been stored at home before purchasing.
