Input:
Very sturdy, easy to clean, so perfect for my 6 year old son. It comes with a container large enough for salads or fruit storage and a seperate tray on top for a sandwich. The thermos is also of good quality material and seals well even when shaken. You might want to add an ice pack because the box is not designed to keep food cold.
