  • Description

    Flat stacks stack flat.

    We don’t mean that in a Dr.Seuss kinda way. They actually do. You'll save more than double the space in your kitchen and keep your cupboards tidier than ever. When full of food, they can go as high as 3 and 1/2 inches, and when collapsed can then magically scrunch down to a teeny tiny inch.

    Have you ever dropped a tupperware-like hybrid container that are a dime a dozen? They crack and crease, and sometimes just shatter. You certainly get what you pay for sometimes. With Flat Stacks, the small investment is well worth it as their well-engineered design is both ergonomic and tactile. The flip and clip top covers seal in food making them 100% leak-proof.

    Some plastic containers are actually embarrassing. They can look shoddy. When flat stacks are brought to a barbi or pot-luck get-together they can make the food look even better. They even look awesome in the cupboard, no matter what your favourite colour is. It’s like an instant facelift for your kitchen cabinets.

    They will not smell like curry six months after you keep cooking your trademark favourites. We know this because every single person in Wowzr HQ is either an avid cooker or an epic eater. We know our food. These storage containers will outlast most of your other off the shelf plastic containers.

    We all have a nightmare shelf or a ‘third drawer down’ with stuff we don’t like but can’t bear to throw away. Or where unidentifiable tupperware lids end up. Recent unverified research indicates that 96.8% of people who own generic plastic containers can’t find the lids. Same research suggests YOU can save up to 80% of your time in the kitchen with the ease of preparing food, and storing leftovers, cleaning them afterwards (and looking for lids).

    Flat stacks are 100% airtight, 100% leak proof

    Most containers claim to be airtight, but that puddle on the floor tells a different story. Unlike the other guys, Flat Stacks actually are airtight and leak proof, so liquid doesn’t get out, and oxygen doesn’t get in. No spillage and your food stays fresher for longer, thus saving you money on every shop!

    With Flat Stacks, it’s simple to organise your nightmare-ish shelves and cupboards.  

    They are space-saving, stress-free and super efficient. You can store your food expanded or collapsed, you can store food in either an expanded or collapsed position, saving you all kinds of space. You can even serve dinner in a Flat Stack, if so inclined. Just set it on the table and help yourself. Leftovers? Simply drop it down with the food inside, pop the lid on, and it goes straight in the fridge or freezer.

  • FAQs

    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.
