Microwave ovens should not use aluminum foil or other metal containers. Make sure it's a microwave or a light wave oven.
1. The microwave oven can only use one aluminum foil meal box at a time.
2. The lunch box should not touch the four walls of the microwave oven. (at least 2cm away from the microwave wall)
The lunch box should be in the middle of the microwave. (note: if your microwave is metal, place a ceramic or glass tray under the tray.)
4. Food should be spread all over the meal box (at least 80% of the capacity of the whole meal box).
5. Please tear off the aluminum cover before use (open the cover and do not close it for heating).
