Our lunch box with name is both dishwasher and microwave safe. When you click the bento box out of the outside, you can also choose to only put this part in the dishwasher, thus saving a lot of space in the dishwasher. If you want to heat the meal in the bento box in the microwave, this is no problem. However, be aware: only the insert tray is microwave safe, which you can easily click out of the lunch box.
