Got this for our usual leftover needs. 
Love the different shapes and sizes. 
They work wonderful at keeping food and sauce safe and it doesnt leak out. 
I prefer glass containers the most because it wont stain and its easier to clean up. 
I love that the glass containers themselves without the lids are safe to put in the oven. 
I used two small glass dishes to make some cornbread and it worked great. 
Love having containers with more than just one purpose. I can bake with them, use them to store leftovers, and heat stuff back up with them. 
I am really happy i got them.
