In exchange for my unbiased opinion I received my Aqua Light Food containers at a discount. These containers came in a set of 4 of different shapes and sizes. Their lids are fitting and snap closed. They hold various types of medicum including solids and liquid. They can be used in the microwave as well as the freezer and refrigerator They are convenient for on the go storage. Take your meals with you to work or on a picnic with friends. These can be washed by hand easily and clean very well in the dishwasher. They are perfect sizes, not too small and not too big. They really are great and anyone can use them. they would even be awesome for craft supply storage or organizing sewing supplies. These can be used for many things not just food but are perfect for your food too.
