Prep & Store - Set of 3

The press-down lid creates an airtight vacuum seal, locking in your food and keeping it fresher for longer.

To seal: Press the lid down firmly at all corners.

To open: Lift the venting corner first to release the seal.

Important: The vacuum seal only works when food is at room temperature or cooler. Hot food releases steam and moisture, which prevents the vacuum from forming. Let food cool before sealing to ensure it is fully leakproof.

We have all been taught that metal cannot go in the microwave but this type of steel, combined with the smooth and rounded shape of the steel boxes, means they will not cause sparking and are safe to use in the microwave. They have been certifid microwave safe and no microwaves were harmed in the process!

Do not use in older 915 Mhz Microwaves

We advise washing all parts with warm soapy water before you use them for the first time.

Any major dents or deep scratches could make it unsuitable for the microwave, get in touch if you’re not sure.

Do not place any cutlery or foil with the boxes in the microwave, as these will cause sparking.

Avoid contact with any metal surface when microwaving, including a metal plate, metal racks or the microwave wall, this can cause sparking or burn marks on the box.

Use microwaves up to and including 1000W.

The box will be hot when you remove it from the microwave so use oven gloves or a tea towel to protect your hands.

If heating with the lid on, lift the venting corner slightly first to let steam escape safely.
