Prep & Store FAQs
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 tested rigorously and no microwaves were harmed in the process! *Please note : only the base of this product is microwave safe.
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.
No, the lid is not microwave safe. Use a plate or a reusable stretchy silicone cover to stop splashes & spills. Don’t use foil as this could cause sparking.

Excellent quality with a comforting feeling you are helping the planet and your kids!
Excellent quality product which delivers exactly what I? Need for family batch cooking. The seal is superb, and the size just right for a couple of meal portions. It’s a great bonus that the container can be used directly for reheating.

I really like it
I really like it, but through no fault of its own, my arthritic hands struggle a bit to open it when ive released the suction.
Really great container. Was completely leak proof on a recent trip, easy to clean and a really good size. The silicone seal together with the clips and band made me feel confident in its ability to stay leak proof and it’s all really easy to clean afterwards too.
