I received this as a wedding gift and I remember making gratin in it twice. After moving, I stored it on a high shelf and forgot about it. I rediscovered it during the end-of-year cleaning, and I'm putting it up for sale in hopes that someone will use it. There are marks that look like wrinkles from the manufacturing process. They do not affect the inside. Please check photo 7. I would be happy if you could use it for gratin in the cold season, or as a serving dish for salads and other dishes. I washed it with hot water and wiped it with kitchen alcohol. I look forward to hearing from those who understand the above and are willing to purchase it. Thank you.
