Title : Delivers all it promises. Is quite small.
Comment : I really like this container. It didn't get full stars as the top kind of 'indents' and compresses some food/ can't fit as much in it. The glass bottom is great for around the house use and i like having the lid for saving food (eg, saving leftover hummus or dips).
