Square Heat Resistant Borosilicate Glass Lunch Box With Anti-Leak Lid- 520ml

These food containers are heat-resistant and made from borosilicate glass, which is even more shatterproof than tempered glass. This glass food container with lids locked on four sides by an airtight seal avoids spills of food, whether that be in your fridge, oven, or if you're snacking on the go. It is suitable for high or low temperatures and completely safe to use in the freezer, oven, and microwave without a lid.
