Rectangle Trio Containers Pack (3-pc)
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.
How They Work
Pop them open and fill them with leftovers, meal prep, snacks or lunches.
Clip on the colour-coded lid and push the valve down for an airtight seal.
Squash them down as you use them, then fold them flat to store when they are empty.

Watch Flat Stacks fold, stack, cook and store in real kitchens.
These bundles include this pack, for less than buying each piece on its own.
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.

Yes, soups, stews and sauces included. Clip the lid on and push the air valve down for an airtight seal. When you carry them, keep them upright and don't squash them into a full bag, so the pressure doesn't push liquid out.
Send them back. Every order comes with our 30-Day Money Back Guarantee: if you're not completely happy, return your purchase within 30 days for a refund.
