450 ml microwave safe stainless steel box

Waterproof and airtight. Ideal for storing, transporting, and reheating your meals. The valve on the top of the lid makes it easier to open and close the box and guarantees a good seal. Precautions for use: remove the cover before heating in the microwave. Do not heat more than 3 minutes in the microwave. Use a pot holder or gloves to hold the box when it comes out of the microwave to avoid any risk of burns.
