Round Sunset (4-pc) — 350, 540, 800 & 1200 ml

Some things just make life more beautiful. Like these New Round Sunset Flat Stacks collapsible storage containers in bold, vibrant red and pink hues that help solve your kitchen struggles. Compact, colourful, and ready to save space & simplify your container cupboard.

We didn't just pick red. We chose a shade that captures that perfect moment when the sky burns with possibility — soft enough to feel warm, bold enough to make a statement.

It's the colour of those golden moments: sunrise coffee, weekend adventures, quick lunch breaks that keep you going.

This isn't just a container colour but a mood, a feeling — a little slice of Australian spirit tucked into your kitchen.

What Makes Them Awesome:

  • Shrinks down to nothing (bye-bye, cluttered cupboards)
  • Four sizes that get your food game sorted
  • Tough enough for work, cool enough for home
  • Keeps your food fresh, no dramas

Your Hunger, Your Sizes:

  • Lunch Buddy (540 mL): Midday fuel sorted
  • Meal Hero (800 mL): When you're properly hungry
  • Weekend Warrior (1200 mL): Meal prep central

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

Absolutely love my flat stack. I now have the full range

Hi Coygirl, thank you for your kind review, so glad you are happy with them. We think you may have accidently put 1 star instead of 5, if you feel they are worthy of 5 stars, please update this for us!
Best wishes from the Flat Stacks Team.

Space saver

I have these containers and I love them, if I have a small amount left over after a meal I put it in one of the smallest ones and collapse it, you have a choice of different sizes for large amounts or smaller amounts.

The item for storage purposes is good, but doesn’t have a solid seal so dies leak some when traveling. Mostly a problem when taking left overs for lunch.

Impressed, these are great 👍

Customer Service is LESS THAN DESIRABLE

I received multiple sets. I did the light wash as insert instructed and the large green top no longer snaps to the large green bottom. I've sent 2 emails and called whenever I could--the time difference makes it hard with my schedule--and I've gotten nowhere. Aside from not being able to use the large green stack, I'm happy with the other stacks. I've kept my larger containers from the other brand to be safe, because I'm just a bit nervous.

Love 'em!!

I love everything FlatStacks makes! I'm especially glad to have these jumbo ones as we approach Thanksgiving!

Disappointing

My husband used these in the top shelf with at least a 50mm gap from the top and the dish is destroyed. I certainly wouldn't use it on a BBQ as suggested if this is what it does in an oven.
