Stays strong with hot or cold food!
Size: 18oz brown
Love these bowls! No extra curl on the lip which makes it easier to drink the leftover milk after eating all the cereal, lol!

The difference between 16 oz. and 18 oz. is hard to detect.
Size: 18oz brown
These bowls don't appear to be 18 oz. In fact, they look like they're smaller than my "paper" 16 oz. bowls. Perhaps they are deeper. Still, when I put food in them, they hold pretty much what the paper 16 oz. ones do. I chose them, again because I thought I made a mistake previously to this order. I wanted the sugar cane, heavy duty, microwavable bowls that these are advertised to be. Everything is as described except the size. I'll have to make note that I shouldn't buy these because the oz.'s advertised will persuade one to buy them.
