These food containers were designed with a strong focus on convenience. Made of borosilicate glass, they can be used to both store and heat up food. The containers plus lids are microwave- and oven-safe and they can be cleaned in the dishwasher. When used in the microwave, the lid can remain on the container, with the steam escaping through the opening in the middle. Side handles integrated into the heat-resistant silicone lids make it easier to take out the heated containers.
