Discover the ease of an organized kitchen.

The signature set of Flat Stacks includes 4 different sizes of rectangles to suit many meal and snack needs. It is perfect for full meals on the go and even smaller snacks.

Flat Stacks collapse down while not in use to save up to 60% of space and help keep you organized. Flat Stacks also have matching colour-coded lids that can stay attached while stored. This will save you time searching for matching lids and containers.

Flat Stacks are 100% BPA and BPS-free, so it’s safe for you and your family. They’re microwave, dishwasher, and fridge/freezer safe making leftovers and cleanup a breeze. The top valve can be closed to seal contents inside the containers or opened to vent air out as well. This keeps food fresher for longer and is great for use in the microwave.

Care & FAQ's

  • The seal on my lid comes out in the dishwasher.
    The seal in the lid does come out for cleaning purposes. If food was trapped under the seal and it was not removable, there would be a potential for mold to build. We would suggest removing the seal prior to placing the lids into the dishwasher to ensure they are not lost or damaged. When replacing the seal, ensure the seal is inserted on its narrowest side.
  • My lids seem to be warping?
    Always use the top rack of the dishwasher, if you choose not to hand wash this product. This will prevent the lid from becoming too hot and changing shape. Even though Flat Stacks are dishwasher safe, like any item, hand washing provides product life longevity.

I purchased these items at the Toronto home show. I asked about the containers staining and was told they do not. The first time using them the containers and lids stained. Also the first time I put them in the dishwasher the lids warped and now the containers are harder to collapse. I have reached out by email and not received any response.

Hi Aleisha, we appreciate you reaching out to us about your experience, we are sorry you are not happy with our Flat Stacks. We apologize for our delay in responding, our customer service team is small but mighty! Please know you will receive a response today. :)
