*On the BBQ hot plate, never over an open flame.
No more rummaging through a jumble of bulky tubs and odd lids. Flat Stacks fold down concertina-style with their lids on, so they stack neatly side by side and you can grab the one you need at a glance.
Clip the lid on and press the air valve for a seal that keeps leftovers fresher for longer. Less food in the bin and less money wasted on every shop.
Back from the shops and the fridge is full of half-empty containers? Normally you'd tip the leftovers into smaller tubs, then wash up the big ones. With Flat Stacks, just squash them down to fit what's left and slide them back in. Instant fridge space, no extra washing up, and a lifesaver for the Christmas leftovers.
Each container clips into its own matching lid, so you grab the right one first go. Store them with the lids on and the lid hunt is over.
Thick, rigid, food-grade, BPA-free silicone that holds its shape, even when it's full. Many cheap copies use thinner silicone that folds under the slightest pressure and can crack along the fold lines. Ours resists stains and odours, and is backed by our 5-Year Replacement Warranty and 30-Day Money Back Guarantee.
The all-silicone build goes in the oven, air fryer and microwave, and on the BBQ hot plate*, then straight to the table.
*On the BBQ hot plate, never over an open flame.
Watch Flat Stacks fold, stack, cook and store in real kitchens.

Flat Stacks are incredible! I can now cook and save leftovers without the dreaded lid search! The containers seal really well, and my favourite thing, when they drop onto the floor from the freezer they don't shatter! So good!
My grandchild removed three of the valves from the top of the lids. I sent a message asking if they had replacements; they sent me five at no additional cost. How fabulous is that? Thank you.
I really like them, makes my cupboard so neat and I love the way I can seal them down to half the size
Great size, love it, can use it from mix to oven to fridge.
Great for storing soups and salads ... Love how space saving they are as well
I purchased these for both home as well as the caravan. I find them perfect for both. Exceptionally good quality, love that the colours match the container and lid. Highly recommend.
They are so much better than the cheaper ones ... that is why I have bought more.
Absolutely love these 😍 after ordering I had delivery within a few days. I have chucked all my old containers away and freed up a lot of cupboard space 😀
The best little set for snacks on the go and I love the colours!! I have all my original sets from over 10 years ago and couldn’t be more stoked with them!
Absolutely love our flat stacks, I’m a nurse and these are so good for meal prepping for the week. So much easier to store than plastic containers. Everyone is always asking about them, I love them and always recommend.
Flat Stacks is an Australian family business run by a mother-daughter team. Julie, a mum of three, started it after one too many hunts through the container cupboard for a matching lid. She spent twelve months testing and improving the containers in her own home before we launched in 2014. Today Julie and her daughter Courtney run Flat Stacks together, and they both use them every day. Every order ships from the Gold Coast.

Copies can look similar online, but you feel the difference in your hand.
Flat Stacks food containers have food-grade silicone bases and clip-on, BPA-free hard plastic lids. They go in the fridge, freezer, microwave and dishwasher. Lift the air valve before you microwave to let the steam out.
They don't go in the oven. For the oven, air fryer or BBQ hot plate (never over an open flame), choose Flat Stacks Ovenware: it's all silicone with soft silicone lids, so one dish goes from the oven to the table to the fridge. Washing the lids by hand where you can helps them keep their shape for longer.
