These are on the small size so I purchased these to use for salad dressing. Summer = swimsuits = uh oh I should have started eating salads a few months ago. Perfect size for not only salad dressing but for some toppings I like to add that will get mushy if I add them right to the salad hours before I eat it. Cheese, chopped olives, chopped peppers. Everything is fresh when I add it then. The lids seal tight, the plastic is solid enough to not break easily and is good for using multiple times. The lid has a little flap on it, makes it easy to open and close. Each container holds around 4 tablespoons of salad dressing, or more. There are 24 in a pack.
