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.

Awesome products. Im using these in my campee trailer

Awesome for camping and caravanning

Wonderful space savers in the caravan and don't rattle around, great for putting in breakables to protect them when travelling.

New Storage Containers

I received the flat stacks in timely fashion. So far they are exactly as they are described. I bought them from a suggestion from friends who are also very hpaay with the product. Thank you

They are obviously good quality however they are much smaller than I thought. I know what the sizes were in the advertisement but I’m still working in inches. I am over 80 years old and still talking old money. I only am cooking for myself these days so they will be fine for what I need, but they’re definitely too small for a family of four. I’m just glad I didn’t throw out all of my other containers because I would definitely need some of them I paid $179 Australian. I thought it also came with a cookbook which didn’t come in the package.
