Reusable until it's not

i like that they are perfect for freezing meal size portions. They go from freezer to microwave easily and tomato based ingredients don't stain the black container. After a few months they do deteriorate so tossing is no biggie since they are so inexpensive to replace

FROM FREEZER TO MICROWAVE

These containers are great. They're exactly what you need to freeze leftovers you don't plan to eat the next day and have them ready to microwave. Another good idea for these is to take them to family food gatherings and use for your take home food items. Packaged for fridge or freezer storage when you get home and pop in the microwave.

Different plastic than takeout plastic

these are really nice and make meals become even more affordable buy making it possible to make more at one time and freeze or frig for another day. Great for letting family out friends take home the leftovers from the family meal. Now, when I'm making a family meal for my grown and visiting children, i make enough for them to take home.
