Absolutely gorgeous, will be buying more - happy to retire some old containers even though theyre still functional they don’t bring you joy like these flat stacks do.

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.

Disappointing

My husband used these in the top shelf with at least a 50mm gap from the top and the dish is destroyed. I certainly wouldn't use it on a BBQ as suggested if this is what it does in an oven.

Great!

I'm switching from plastic to silicone, and this really helps. Easy to store, love the colors, and they do fine in the dishwasher.

Great product!

Great quality love the way they store so compact so enjoyable to use

Great product

I’m giving them as Christmas gifts to all my family!

Love them..this is my second lot.
