3-Compartment Stainless Steel Lunch Box with Steel Cutlery, Insulated for Office & Travel – MySmartiee

The built-in water injection feature makes it easy to heat or cool. Simply add hot or cold water into the bottom basin before breakfast, lunch, or dinner! The bottom bowl is made of food grade PP and can also be used to hold fruits or salads. The lunch box itself does not have a long-term heat preservation effect, it needs to be added with hot water to achieve heat preservation.
