I received the Pyrex  FreshLock Plus Glass Storage with Microban in a 10 Pc set. This set is good is if you have one or two things left over and can store perfectly instead of a big container. The square one I held a whole 8pk of franks in there just fine along with corn on the cob I use another for too. The 2 tiny round ones can be for dipping sauce. They are useful and versatile to use.
