I use this 12 oz bowl for a large number of things, from scrambling eggs to cereal to baking an individual quick microwave cake. I actually ordered 5 of these (one unintentionally that I had in my basket and a set of 4). One of the bowls has a flaw in the lip - and it appears to have been chipped and a repair attempt made, as it is not sharp but rather mostly smooth as if it had been buffed or heated and melted. It is not worth the hassle of shipping it back and it is a small flaw and does not reduce the usefulness of the bowl.
