A 9″ bowl is a medium sized bowl that is generally the favorite size for serving to 4-6 people. Unless, of course you have a teenager in your house, then this is a cereal bowl for one. If you’ve had one in your house, you know what I mean. I can’t promise they will do it, but these are capable of going into the dishwasher and put away. Microwave, oven, refrigerator, you can cook, warm or store in a bowl.
