Many kid bento boxes include airtight or leak-resistant seals plus locking clips or latches. Several models also add cooling options such as a removable freezer/ice pack or a built-in insulated pack to help keep food cool.
Common inclusions are utensils (forks and/or spoons, with some models offering built-in or snap-on toddler utensils), divided or removable trays, and—on chilled models—a removable freezer/ice pack. Some salad-style boxes also include a small dressing container and a reusable fork.
