Our Bentgo Kids lunch boxes are leak-resistant for thicker liquids (peanut butter, jelly, and other thick sauces) but NOT watertight for thinner liquids like soy sauce, broth, clear soups, water, fruit, and vegetable juices, etc.
We recommend that you place them in a leakproof bag or foil paper if you are packing fruits or vegetables to avoid the juices from leaking into the other compartments.
If you have any further questions, please reach out to us by submitting a ticket or calling 1-657-275-3734 Monday through Friday 8 am PST to 5 pm PST.
