800ml Rectangular Store and More Container 5 "Excellent product" 12 November 2018 I have the rectangular and the circular containers. I love them for freezing bulk cooking, picnics etc. Especially useful is the fact the compress when empty, great for storage. The first time I used one, I tried to put the lid on as I would with any container. Too much pressure caused the container to compress and some of the contents came out. I only did this once! These are the best containers I have ever bought.
