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.
Yes, the silicone tab make a vacuum seal which means they are 100% airtight and leakproof. To create the vacuum seal, press the lid down firmly with the tab open and then press the tab down. To release the seal, simply pull the tab up and remove the lid.
Yes, the Prep & Store boxes are safe to use in the dishwasher, freezer, & the bases are oven-safe. When freezing, take care not to over fill, particularly if meal prepping liquids as they can expand when frozen.
All our stainless steel products come with a 15 year warranty. Glass and silicone isn’t covered, but we sell spare silicone lids for Seal & Go Range, spare silicone bases for the Lunch Bowls and tabs for the Bowls & Prep & Store Range.
I love this size box. I have five of them now and use them daily.

Perfect for a spot of leftovers for lunch!
A perfect size to take lunch in. Air and water-tight. I plucked up courage to put it in the microwave! Worked a treat. Then no leaks in my bag afterwards. Also fits and stacks with other similar boxes in the freezer so very versatile.
