I use these for storing many things in my freezer...soup, chili, spaghetti sauce, etc. They are the perfect size for a serving for 2 (at least). I have been using these for many years and find them perfect for liquids and solids. However, I do have to say I do place them in an upright position, so can't dispute other reviews that say they leak when carried in a backpack, etc., but for freezer and refrigerator storage, they are "just the ticket"! I also love them, because they are reusable and reasonably priced.
