FAQ

How does it work in the microwave?

Yes, you read that right, these steel boxes are microwave-safe. We know that everyone was taught that metal cannot go in the microwave, but it’s only partly true. There are definitely some metals that should not be placed in a microwave, however, this does not include the high-quality stainless steel that we use. 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 adhere to extremely high safety standards and have been tested rigorously.

Is there anything I need to know about microwaving these boxes?

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.
• We advise washing all parts with warm soapy water before you use them for the first time.
• Any major dents (and we mean major) or deep scratches could make it unsuitable for the microwave, so watch out for these.
• Do not place any cutlery or foil with the boxes in the microwave, as these will cause sparking.
• Please ensure you only heat one box at a time for a max of 2 minutes before stirring to repeat. 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.
• If you microwave for longer than 2 minutes it could cause the polypropylene lid to warp, which will then affect the leak proof performance.
• Avoid cooking food which heat to extreme temperatures like popcorn or sugar, these can cause burn marks on the stainless steel and plastic lid.
• 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.
• Please note that heating very oily/acidic food (such as tomato soup) may cause staining and even burn marks on the lids.
• Do not use box in the microwave when empty.
• 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. Are there any foods I should avoid when using these boxes in the microwave?

You should avoid foods that heat to extreme temperatures, like popcorn or sugar, as these can cause burn marks. Also, please note that very oily or acidic food (such as tomato soup) may also cause staining and even burn marks on the lids. Please note that burn or stain marks will not affect the functionality or safety of the product. When microwaving any acidic foods, stir frequently to avoid splashing the lid and limit microwave time to 2 minute intervals.

Can I also microwave the lid?

Yes! We have specifically designed the lid to remove the need for single-use plastic cling film to prevent splatter when microwaving. Just ensure the lid lock is popped open (to prevent pressure build up and to release steam), and you’re good to go.

Can I put it in the dishwasher, freezer and oven

Yes, yes and yes. The meal prep sets are dishwasher-safe (lid is top rack only), freezer-safe, and the steel box is oven-safe (not the lid). When freezing, take care not to over fill, particularly if meal prepping liquids as they can expand when frozen.

Are these boxes leak proof?

Absolutely, this is an incredibly important feature to us. Leak proof means peace of mind, and there’s no point using a reusable lunch box if you need to wrap it in a plastic bag! 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. Win-win!

How do I open the lid?

These steel boxes are leak proof due to the vacuum seal in the lid, but this can mean they are hard to open (nearly impossible actually until you break this seal). You break the seal by simply pushing the button to release the lid lock. You will find the lid opens more easily if you pull it upwards slowly rather than quickly.

How do I look after my meal prep sets?

Be careful not to use sharp objects like knives directly on the steel as this can cause scratches. 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. All seals and the lid lock valve (the grey silicone part ONLY, do not remove the actual lid button) are fully removable for deep cleaning. We also advise washing all parts with warm soapy water before you use them for the first time.
