Starter Pack > Signature Set + Air Fryer Ovenware + Snack Pack with FREE Oven Mitts

The last batch i bought lasted 3 years with constant use so of course I had to get more

If course, i like the stackable ability of the containers, BUT the starter pack arrived, and they are so small they're basically of no use to me. The largest container is the size of a lunch box. I thought i would be able to make lasagne or potato bake in or fit left overs in them. Great, if you have tiny kids or babies, i guess, but to me, it was a waste of money, and they aren't cheap. I would mind the cost of they were practice sizes.

Hi, we are glad to hear you are liking the Flat Stacks. However, we do have a range of sizes for our ovenware range our largest being 7L, if you feel you have gotten the wrong size, please email us, so we can help you further.

OMG

My husband and I are down sizing and I can’t believe how many containers I had collected over the years. Now I can put my stacks in a small drawer and not have to find the lids to them. Loving the round ones.
Thanks Flat Stacks. Best buy ever
Can’t wait to order more
