FAQ’s

How does it work in the microwave?

Yes, these boxes are microwave-safe! The high-grade stainless steel and rounded edges prevent sparking. The vented lid lets steam escape, reducing heating time while keeping your microwave clean.

Is there anything I should know before microwaving?

Yes. Do not use in old 915 MHz microwaves. Only microwave one box at a time, for up to 2 minutes before stirring and repeating if needed. Always pop open the lid lock to release steam. Avoid heating sugar, popcorn, or very oily/acidic foods as they may cause staining or burn marks.

Can I also microwave the lid?

Yes. The vented lid is designed to stay on while microwaving to prevent splatter. Just make sure to pop open the lid lock before heating.

Can I put it in the dishwasher, freezer, and oven?

Yes. The steel base is oven-, freezer-, and dishwasher-safe. The lid should go on the top rack of the dishwasher only. Do not oven the lid.

Are these boxes leakproof?

Yes - 100%. The vacuum-sealed lid keeps food secure and air-tight, making it ideal for transporting meals or reducing food waste through better storage.

How do I open the lid?

Push the button on the lid to break the vacuum seal. Then lift slowly from the corners. This releases the pressure and allows the lid to come off easily.

How do I care for my lunch box?

Avoid sharp utensils inside the box. Don’t use bleach, abrasive cleaners or scourers. All seals and the grey silicone valve are removable for deep cleaning. Always wash all parts in warm soapy water before first use.

Are there any foods to avoid microwaving?

Yes. Avoid microwaving popcorn, sugar, or anything that reaches extreme heat. Very oily or acidic foods like tomato soup may stain the lid- stir frequently and microwave in 2-minute bursts to reduce staining.
