Thank you for viewing. Tamagoyaki (Japanese rolled omelette) frying pan. The manufacturer is unknown. Used for making bento (boxed lunches). It hasn't been used that many times, so I think it's still usable without any problems. I haven't cooked anything other than tamagoyaki in it. There is some burning on the back. I would like to pass it on to someone who can use it again. Gas stove only, not compatible with IH (induction) cooktops.
