The casserole was slightly smaller but for my family it worked. The chapatis are folded and kept in it. I would say about 10 chapatis would fit in it if they are folded. The food remained warm for about an hour or so. I bought this because I wanted something smaller in size as that is easy to clean. Being Milton, I assume it would be durable and value for money. After a month of using, my family is okay with it.
