    Is there a difference between the lunch boxes and other containers?

    Yes. The lunch boxes have a number of compartments that keep food separate, and they come with cutlery. The regular containers don’t.

    What does BPA free mean?

    BPA is an industrial chemical, often used in plastic consumer goods like water bottles and containers. Some studies have linked it to various illnesses. BPA Free means BPA hasn’t been used in the production of the container, and so is totally safe for your family to use.

    Do I need to use special settings to put Flat Stacks in my dishwasher?

    Nope. Just run it with your regular load, and watch it come out as clean and fresh as it was when you bought it.

    Is it difficult to collapse the container? Will it stiffen up over time?

    It’s easy as pie to collapse or expand Flat Stacks. You simply push and pull. They’re made of silicone, so they are built to last.

    Can I handpick the colours, shapes, and sizes I want, or do they come in specific bundles?

    With Flat Stacks, you get four awesome options:
    1. Four rectangular containers, ranging from small to medium.
    2. Two large rectangular containers, perfect for family dinners.
    3. Four round containers, ranging from small to medium.
    4. Two lunch boxes (one pink, one blue) with separate compartments.
