this review title is: they are a little bigger than advertised i measured ounces and the content is: these are four 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.there are other information for this review, one is this reviewer did not purchase it and the other is 2 people think this review is helpful.
