100% FOOD SAFE - Interior is 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 exterior and dividers are made from food-grade safe plastic.
LEAK & SPILL PROOF - Between each stackable compartment are heavy-duty silicone seals to lock in freshness, leaks, and odors. Each layer also has an individual lid which not only reinforces its leak-proof feature but also prevents messy food on the bottom of the above layer.
MULTI-FUNCTIONAL – The exterior layer is microwavable. You can either use the exterior layer only which can be used in a microwave or use the stainless steel liner to hold the food, depend on your preference and the food you are going to take.
UNIQUE DESIGN – Please note this is not an insulated lunch box, so it can only keep food warm for about an hour. If you want to use it for hot food, you can add hot water between the interior stainless steel container and the exterior layer to keep your food warm for up to 1-2 hours.
After washing the lunch box, please let it dry first before putting all the parts back together.
It is NOT recommended for ice/ice cream.
Please note this is NOT an insulated lunch box. So it won't keep the food warm for a long time.
