In my house left overs are a major thing, they mean lunches the next day or Mom doesn't have to cook nights. I needed a food storage that could go any where and not take up too much space. I love my easy find lids. My family has that nasty habit of never putting the right lid with the right container, but with these I don't have to worry about it. I have the large 2 gallon size for my cake decorating classes, the tiny ones hold condiments for my husband's lunch bag, and never once has a container been dropped and broke open. There are some downsides, they don't lock out all freezer burn but the do it better than a plastic bag and reheating food in them can cause them to become pitted, but even with these small problems they are better made than some of the other food storage containers I have tried that didn't do anything but break and melt on the first use.
