Thank you for viewing. This is a gratin dish from Nitori. Approximately 26cm in diameter, 5.5cm deep. I purchased it from Nitori over a decade ago. I'm not sure how many times I used it, but I used it a few times a year for 2-3 years. After that, it was stored at home for a long time. There is a stain on the bottom that won't come off even when wiped (image 4), but otherwise, it is in relatively good condition without any noticeable scratches or stains. Please consider purchasing if you understand that this is a used item.
