So far so good

Much easier to close than the rectangular ones and lids seem more robust. The rectangular lids keep breaking.

Excellent product

We have just remodelled our kitchen and with the change of storage options these Flat Stacks are perfect. No more is the mess of trying to fit all the different Tupperware containers into a cupboard or drawer. Now everything is tidy and taking up less space.
