I have had some of these for many years, and they are such a useful size that I finally had to buy more of them.  They are the perfect size for storing some of the things l make (like cream of chicken soup in recipe-size portions) and also the perfect size to hold a meal-sized serving of one of the dinners I make.  I love that they are oven safe, freezer safe, microwave safe.  These might be the most useful containers I have.
