3 in 1 Compartment Design Our bento box is double-layered, with three detachable compartments, including 1 large container and 2 small containers of the same proportion. Each layer has an independent airtight lid to prevent food from mixing, helping to maintain the original taste of food. High-quality Materials The 1400ml kids' bento lunch box is made of food-grade PP material, which is safe and durable. The bento box is microwave-safe, dishwasher-safe, and freezer-safe. It also includes a fork and spoon. Leakproof Design Each container of this bento lunch box has a divider for good airtightness. It is recommended to open the ventilation valve before removing the divider to reduce the air pressure difference between the inside and outside of the container, making it easier to open. (Tip: This bento box is better suited for storing dry and slightly soupy foods.) Portable and Easy to Clean It is easy to clean by hand or in the dishwasher, although the cover lid is recommended to be hand washed to avoid scratches. Microwave-safe for 2-4 minutes at up to 212F. (Note: Lids should not be placed in the microwave.) Wide Use This lunch box is specially designed for balanced and healthy meals. It is perfect for kids' school lunches and adults' on-the-go meals, ideal for work, exercise, camping, and traveling.
