- There are definitely some metals that should not be placed in a microwave, however, this does not include the stainless steel that we use.
- Use microwaves up to and including 1000W.
- 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.

Product Details
The meal prep sets are dishwasher-safe (lid is top rack only), freezer-safe, and the steel box is oven-safe (not the lid).
How do I open the lid?
You should avoid foods that heat to extreme temperatures, like popcorn or sugar, as these can cause burn marks.
It will take slightly longer to heat your food in these boxes than regular plastic or glass, however as the lid can stay on (with lid lock open), they are faster than other steel boxes to heat.
Also, please note that very oily or acidic food (such as tomato soup) may also cause staining and even burn marks on the lids.
Avoid cooking food which heat to extreme temperatures like popcorn or sugar, these can cause burn marks on the stainless steel and plastic lid.
If you microwave for longer than 2 minutes it could cause the polypropylene lid to warp, which will then affect the leak proof performance.
They adhere to extremely high safety standards and have been tested rigorously.
Are these boxes leak proof?
Do not use bleach, cleaners containing chlorine, abrasive cleaners or scrubbers on any part of the box as they may dull the finish and cause scratches.
Source configuration: SMALL-MEDIUM-LARGE.
Can I put it in the dishwasher, freezer and oven Yes, yes and yes.
The vacuum sealed lid lock ensures this range is 100% leak proof and airtight, which also means your meal prepping will stay fresher for longer, additionally reducing food waste.
Is there anything I need to know about microwaving these boxes?
We have specifically designed the lid to remove the need for single-use plastic cling film to prevent splatter when microwaving.
Innovative microwave-safe steel container (not suitable for combi-ovens, see FAQs for more info).
Be careful not to use sharp objects like knives directly on the steel as this can cause scratches.
