HI. I'm looking to buy some glass tupperware-like containers for food
storage that can go in the fridge as well as freezer. It is important
that they are not round, but have flat sides.  I want to be able to
compare a couple different styles/brands that are of good quality.
Either glass or plastic lids are okay, just as long as the actual
container is 100% glass.  Made in the USA is a plus.

As far as size goes, I'm looking for storage containers, not baking. They'll
mostly be used for storing leftovers.

What are a few different options, and where can I buy them online for
a decent price? Thanks!

Hi, here is one site that 
has exactly what you're looking for,
Onelifemall.com

The airtight storage glass is perfect for freezer, microwave and fridge 
to store all kids of foods.
I find it especially nice to clean and that food never leaves any
stains. The plastic lid with glass combo makes it a practical everyday
item also.
Hope you enjoy it as much as i Do!
