A school lunch has one job: arrive at noon looking like food, not soup. Reviewed reviewed kids lunch boxes by shaking them full of water, logging temperatures for four hours and sending them to actual school, so the bento boxes here are the ones that passed.

Its water bottle picks spent 12 hours upside down and a year in backpacks. The kid-sized food jars come from BestReviews, and the ice packs from NBC Select. Start with a bento box, a lunch bag and a bottle. Add a food jar when your kid wants leftovers warm, and ice packs if the bag isn't freezable. Each card shows the drawback the outlet called out, like boxes that can't fit a whole sandwich.

Who this is not for. Skip this if your kid is still in the sippy-cup stage; the Toddler Mealtime list has the suction plates and sippy cups.

Munchkin Lunch Bento Box

Best for little kids who need a box that won't leak

Questions people ask

Which kids bento boxes fit a whole sandwich?

In Reviewed's test, the Munchkin Lunch Bento Box fits a standard sandwich, and the OmieBox fits one in its largest compartment. The Bentgo Kids Chill doesn't, so pack wraps, pinwheels or cut-up sandwiches in that one.

How do I keep a school lunch cold until lunchtime?

Freeze a PackIt bag overnight: Reviewed found it keeps cold food at safe temperatures without separate ice packs, and says most other insulated bags don't act like refrigeration. Even the Bentgo Kids Chill, with its built-in freezable layer, didn't stay under 40°F for the full four hours in Reviewed's test, so cold lunches need a freezable bag or an ice pack.

How do I keep a hot lunch warm in a thermos?

Reviewed says preheating an insulated food container with hot water helps it keep food at a safe, tasty temperature. Fill it with hot water, let it sit, pour it out, then add the hot food right before school.
