But the reason I'm posting is the container itself. It's got this push-button on top. You push it, it clicks, and pops up, and the seal is open, and you can pull the lid off. Push it again, it clicks and stays down, and the container is sealed and stackable. I don't know how to explain it, but it feels like it's from the future. It feels like kitchenware from a future I would want to live in.
I just wish it came in more convenient shapes. The 5.5qt version is tall and narrow, while I'd prefer short and wide. I bought the 2.5qt because it had the closest proportions to what I wanted.
