    Nice sizes

    Like the different sizes that fit where the rectangular ones don’t.

    Squarely fits well

    Love they fit so well into the freezer or fridge then flatten when not in use. Great colours & size options in this set with the smallest being more useful than l'd thought it'd be .

    Totally love these containers

    I am extremely happy with these containers. They are such a great idea. In the past I have bought containers that I cannot get the lids onto without stepping on them. Then after a while the lids are so loose they won’t stay on. These containers don’t have that problem. Also I love the material they are made out of, they don’t absorb the sauce, they don’t loose their smooth surface. They are way more functional than the competition. And they store away in small spaces. Couldn’t ask for better.

    A bit smaller than I thought they would be, but you can’t beat the quality

    Love them after 3yrs, bought more

    We love Flat Stacks so much we had to come back and buy more. We live in an RV and these are great because they take such little space to store, the lids stay snapped on the containers so you never have to find the lid and they last. We just got rid of our old plastic containers and this is our second time buying this set.
