SUPERIOR TEMPERATURE INSULATION – The vacuum insulation and insulated bag provide up to 6 full hours of warm retention; nearly twice as long as others. NO more cold lunch. NO more microwave. The vacuum insulation provides the right temperature to keep food stay warm and healthy.
100% FOOD SAFE – Interior and exterior are made from high-quality food-grade stainless steel SS304 which will never rust and is naturally BPA-free. It does not retain flavors or scents, so you can use it over & over again. The handle and divider are made from food-grade plastic.
LEAK & SPILL PROOF - Between each stackable insulated compartment are heavy-duty silicone seals to lock in freshness, leaks, and odors.
INSULATED BAG INCLUDED - Made of felt fabric and food-grade aluminum foil-lined interior, it can not only enhance the insulation but also make it easier to be carried around.
After washing the lunch box, please let it dry first before putting all the parts back together.
It is NOT recommended for cold food, ice/ice cream.
It CAN'T be used in microwave or dishwasher.
The coupling between layers is tight to prevent leak and spill. After using it a couple of times, it will become smooth.
A couple of things will affect the insulation: (1), the amount of food in the lunch box and the food's heat capacity. If the food is less than 3/4 of the lunch box, it may reduce the insulation capability. (2), the original temperature of the food put in the lunch box. We suggest heating the food to a temperature high enough in order to provide a good insulation result.
