Right Size, Leak-proof, Easy to Clean: Convenient for children to take and carry. The sealing ring on the seal ensures the isolation of food in the lunch box. The rubber sealing ring can be removed, and its smooth interior is easier to wipe clean than other models. Please hand wash the children's food jar as much as possible. If your child is too young, please do not tighten the lid too much. Multi-compartment & Insulated Jar: The lunch box has 3-4 compartments, which helps keep the food separated and fresh. Our insulated jar is double-walled vacuum insulated, which can keep food hot for 6 hours and cold for 12 hours. The lunch box is very suitable for children and can be put in a lunch box or backpack. Let children enjoy a fun, nutritious and healthy lunch.
