Starter Pack
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*. Cook with the lid on to keep roasts and bakes moist and stop the splatter, then take it straight to the table.
A full glass dish is heavy to lift in and out of the oven, and one knock off the bench and it's gone. Flat Stacks Ovenware is much lighter and easier to handle, and it bounces back if you drop it.
*On the BBQ hot plate, never over an open flame.
How They Work
Pop them open and fill them with leftovers, meal prep, snacks or lunches.
Clip on the colour-coded lids and they're ready for the fridge, freezer or lunchbox.
Squash them down as you use them, then fold them flat to store when they are empty.
