Insulated lunch box with removable divider

I work in an office, where cafeteria (microwave) is on the opposite site of the building. With this insulated lunch box, I do not need to go all the way to the microwave to warm up my food. Especially, I love the removable divider; I can adjust the relative portions of two sections, and it completely divides the two sections without any leakage.
