"Absolutely love my Flat Stacks - Amazing product. I love how much space they save in my cupboards, they're really strong and you can feel the quality of them and they look great in the kitchen. Definitely going to order more and the lunchboxes for the kids. Service was excellent too. Very quick delivery. Highly recommend." - Lisa P
"My favourite thing about Flat Stacks, is when you do cook a big meal, as people eat you just pop it down to the size of the food inside so instead of having a huge container in the fridge or freezer; it takes up hardly any space at all." - Adele L

Say goodbye to your nightmare cupboard and never again feel the frustration of rummaging around trying to find that matching lid. Instead you'll have an organised, colour-coded bliss that will leave you feeling calm and in control.
Flat Stacks are made of silicone. Unlike plastic, silicone is a non-toxic, BPA free material making it safer for your family. Silicone can withstand extreme heat or cold without bending, cracking or degrading and is stain and odor resistant. Flat Stacks will last much longer than plastic containers so you won’t need to replace them, saving you money and helping the environment.
Clip the lid into place and push down the air valve for completely airtight storage that keeps your food fresher for longer reducing food waste and saving you money on every shop.
Leftovers? No need to swap containers, just collapse it down with the food inside and it goes straight into the fridge or freezer for next time. No wasted space, no extra containers and no extra washing up!
Flat Stacks are 100% microwave safe. Simply lift the air valve on top to release the steam. Push the valve down to seal the container making it air-tight before placing them in the fridge, freezer or cupboard.
Never waste your time searching for that missing lid again, Flat Stacks have clip on colour-coded lids.

Yes you can put soft foods and liquids like soups in your Flat Stacks however you do need to be careful not to put too much weight on the container as it could cause it to collapse and squash the food or liquid inside. Be especially careful if you're transporting liquids or squash-able foods in a backpack or bag not to put too much weight or pressure on the container as it could force the valve seal on top to push up and then it could leak.
Flat Stacks cannot be used in the oven because they have a plastic component underneath the lip to keep the container rigid and this would melt in the oven. They can be used in the microwave.
