Lovely colours and good range of sizes. Just bought a 2nd lot to give to my daughter in law for her birthday. My son's family does a lot of travelling for holidays and these will be very handy.

Flat Stacks

We love Flat Stacks containers - they are versatile, durable, leakproof, and easy to store. We purchased a set originally at a Christmas show and sale event, and got a lot of use out of them. We wish we could find them in stores for purchase.

Practical & pretty

Love the square set, good sizes, fits nicely in the fridge & freezer. And love the shades of green 💚
