Thank you for viewing! This is a Cerabeike round dish. The circular part has a diameter of 20cm, and the width including the handles is about 23cm. It's sold as having a capacity of 1500cc. I haven't used it for cakes, but I have used it for things like roasting chicken and vegetables in the oven. Because it's a glass container, you can also preheat food in the microwave and then use the oven just for browning. Even if food does stick, it's Cerabeike, so it washes off easily. There are no cracks or breaks, but there are some slight scratches from cutlery when taking food out. Therefore, I've marked it as "has some scratches and dirt." The scratches aren't large enough to cause the coating to peel off, and I couldn't capture them in the photos, but they are visible to the naked eye, so I wanted to mention it beforehand. It's a cooking utensil and dish with unique features that are hard to replace, but since my family is small, I don't use this size for oven cooking very often. I'm selling it as part of a decluttering effort. It's a used item from a regular household, but it's still perfectly usable, and I hate to throw it away. I hope someone will take it. Please consider it.
