We do a lot of cooking and I was needing some smaller casserole dishes. The size is just what I was looking for. Each has a 12 ounce capacity. I can make different dishes in each or do the same dish with different ingredients (customize to taste and preferences) at the same time. Comes with 4 round casserole dishes with lids. They are oven, dishwasher, and microwave safe. They are not safe for the stove top. We had some leftover stew and I just left it in this dish, put it in the fridge, and then put it in the oven to reheat. Saved us from getting a storage container dirty. I picked out the gray ombre because it goes with so many decors.
