Review title is They are a little bigger than advertised. I measured 4 ounces! [SEP] These are FOUR (4) ounce containers! These are a little bigger than we expected. They will take up more room in a carry-on quart sized bag than I want. However, the bottles and everything that came with them work well as expected. I just wish that the seller would verify information before advertising. I took off only one star for the advertisement disappointment, but I kept the other four stars because the set works well for the size that they are.
