Warm Tips: If your food is dry, it is recommended that you add some water or stock to the food to heat it more quickly and evenly. Open the steam vent cap before heating. Otherwise, the internal steam may cause deformation of the lunch box, or even damage it. Please do not put the heating base into the water or rinse it with running water, in order to avoid short circuits caused by water ingress.
