Great travel containers.

I purchase these for roadtrip travel food containers. I keep them in what I call a travel picnic bag of plates, cups, bowls, utensils, napkins, ziplocs, recyclable storage bags, etc. I can transfer restaurant takeout foods to these flat sandwich size containers so I don't have to try to fit the larger takeout styrofoam, cardboard or foil containers in smaller hotel fridges or coolers which are bulky and don't fit well. They are also good for small college fridge storage. Please do not heat food in these containers, transfer food to paper plate, bowl or cup.

Perfect Storage Containers

Love these containers! They are just the right size for leftovers and newovers. They are great for serving. There is a nice, firm, strong lid for these containers. The containers themselves are very strong and durable. I use them in the microwave also with no problems.
