How does it work in the microwave?

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! 

How do I use these in the microwave then? 

• 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 you might want to use oven gloves or a tea towel to protect your hands.

Can I also microwave the lid? 

No, the lid is not microwave or oven safe. Use a plate or a reusable stretchy silicone cover to stop smashes & spills. Don’t use foil as this will potentially cause sparking. 

Are these boxes leak proof?

Yes, the silicone seal and clips means this range is 100% leakproof and airtight, which together with the naturally antibacterial properties of steel, ensures that your food will stay fresher for longer.

Can I put it in the dishwasher, freezer and oven

Yes, the boxes are safe to use in the dishwasher (lid is top rack only), freezer-safe, and the whole thing is oven-safe. When freezing, take care not to over fill, particularly if meal prepping liquids as they can expand when frozen.
