Product Details
How do I open the lid?
Semi-transparent lid to see your meals clearly.
Please ensure you only heat one box at a time for a max of 2 minutes before stirring to repeat.
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.
We have specifically designed the lid to remove the need for single-use plastic cling film to prevent splatter when microwaving.
This set includes: 1 x 1.1L Box, 1 x 1.4L Box.
We know that everyone was taught that metal cannot go in the microwave, but it’s only partly true.
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.
Use microwaves up to and including 1000W.
These microwavable steel food boxes are leak proof, dishwasher and oven-safe, and come in two sizes for breakfast, lunch, and everything in between.
Easy-clean: fully removable seals.
Yes, there's a few things to consider when microwaving these boxes, from both a safety perspective and also to prolong the life of the product: Do not use in older 915 Mhz Microwaves.
Small - 1.1L - 19.5cm x 19.5cm x 5.8cm - 310g.
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.
Are these boxes leak proof?
Use glass turntable if available.
Be careful not to use sharp objects like knives directly on the steel as this can cause scratches.
