Bargain Alert

Sierra Trading Post currently has the Italian glass storage jars for really great prices. They are available in sizes from less than a liter to a gallon. These come with the rubber ring and seal hermetically.  They are especially good for storing the contents of #10 cans if you don't use it all for your first meal. Because they have a glass body and top, and seal tightly with a rubber gasket, they do not allow oxygen exchange like plastic does.

To find them fast, use the search feature for Bormioli
