I don't recommend these. After about 3mo of use the marks rubbed off of the containers, the lids do not fit well and they aren't high quality leftover containers like you would get from tupperware or rubbermaid. They leak and are hard to close. If you like higher quality leftover containers, you'll be disappointed.
Coincidentally these products are available through by book club this month & I wouldn't have given them consideration before, but after seeing your video and quick demo I'm ordering both!!! Thanks for this timely piece!
