I'm so happy I bought this insulated food container. I packed a pasta for my daughter's lunch and she said it was still steaming hot at lunchtime. It's easy to use, clean, and doesn't leak. The design is sleek and practical. No more cold meals, just warm food ready to enjoy.

very good!

The biggest advantage of this is that the food does not mix with each other. In addition, food is kept warm for a long time. The durability of this lunch box is also strong, so I think it will be used for a long time once I buy it. I like it even more because it's bigger than I thought!

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.
