Are there any foods I should avoid when using these boxes in the microwave?

When microwaving acidic foods, stir frequently to avoid splashing the lid and limit microwave time to 2 minute intervals. Please note that very oily or acidic food (such as tomato soup) may cause staining and even burn marks on the lids.

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! 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.

How do I open the lid?

These are leak proof due to the vacuum seal in the lid, but they are hard to open (nearly impossible until you break the seal). Do this by pushing the button to release the lid lock. The lid opens more easily if you do it slowly rather than quickly.

How do I look after my meal prep sets?

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.
