A storage container that is made of glass and does not have to worry about odors or color transfer.
It is resistant to salt and acid, and the contents can be seen, so it is perfect for storing regular dishes. Microwave OK with the lid on, and if you remove it, you can use it in the oven. This makes me very happy. It's very useful because it can be stored slim in the refrigerator and can be served on the dining table as it is. The appearance of stacking in the refrigerator seems to raise the tension.
