Packing school lunches often involves using several plastic bags or many pieces of aluminum foil, which is wasteful and time consuming. A solution is the bento box, which is definitely a worthwhile purchase if your kids like their food stored separately.
These cute lunch boxes stand out thanks to their numerous compartments, which are sized for all types of foods, from sandwiches to fruit to chips. Many bento boxes are even leakproof, allowing you to pack liquids alongside your child's snacks—ideal for, say, carrots and ranch dip.
Our product test team helped find the best bento boxes for kids you can buy, from budget-friendly to most versatile.
Best Overall: Bentgo Kids Lunch Box
:max_bytes(150000):strip_icc()/BentgoKidsChildrensLunchBox-bae92a637cbf4b9b86b97e797321d51d.jpeg)
Leakproof design
Rubber sides are extra durable
Made with BPA-free plastic
Easy to clean
Slightly heavier than other models
Exterior scratches pretty easily
If you’re looking for the best bento box for toddlers, there are a few extra things to consider. First of all, you want a more durable product that can stand to take a few tumbles if it slips out of their little hands. Second, it’s important that the box is easy to open and close, otherwise you might find yourself cleaning up spilled lunches.
The Bentgo Kids Lunch Box meets all these criteria, making it an ideal lunch box for children ages 3 to 7. The BPA-free plastic bento box has five compartments and can safely be used in the microwave and dishwasher. It boasts a tight seal to keep the various sections from leaking, and you open and shut the box with two secure, kid-friendly latches.
As a bonus, the edges of the box are lined with rubber to minimize impact in case of drops, making it perfect for young children. But just because it is made for toddlers doesn't mean big kids and adults can't use it as well. Our tester noted that the extra protection of the lunchbox made it a touch heavier than others, but it was easily manageable and worth the security. It was also easy to clean by hand since there are no small crevices on the smooth surface of the box.

For a kid-friendly bento box that’s free from harmful chemicals like BPA, you can’t go wrong with the Yumbox Original. This leakproof bento box is designed especially for kids, and careful attention was given to every detail, from the cute colors and illustrations to the easy-open latch.
The Yumbox is made for toddlers and young children and is more expensive than many other options, but it makes up for the cost with great functionality. There are six unique containers in the BPA-free lunch box, each labeled with a food group to help kids learn and help parents figure out what to pack. You can include foods like applesauce without worrying about them spilling out, thanks to the leakproof silicone seal. Plus, the inner shell is top-rack dishwasher-safe. This box also has a small dip container to fill with sauces like hummus or salad dressing.
Our testers liked that this bento box is durable and that its compartments are perfect for various snacks. Most agree that the high-quality design is worth the higher price tag, but a few do note that the surface shows some wear and tear the more you use it, and you may want to hand-wash the box to increase its longevity.

Safe for the microwave, freezer, and top-rack of the dishwasher, this container is the perfect size to fit into the popular PackIt lunch bags. The versatility of these bento boxes is especially great, with many people saying they’re ideal for packing snacks.

What to Look for in a Bento Box for Kids
Material
Bento boxes are made from different materials, each with pros and cons. Plastic is lightweight and easy for kids to handle since it won’t shatter if dropped. Metal is more durable and can withstand high heat in a dishwasher. Glass is both dishwasher and microwave-safe, but it’s heavy and breakable.
Size
Consider how much food you need to pack. It's not necessary to send your kids to school with a bulky, adult-sized bento box that’s half-full, but there should be enough space for everything they like to fit comfortably. If green salads are often on the menu, you’ll need more space than if you pack smaller amounts of denser foods.
Number of compartments
If the bento box has a large number of compartments, you can keep many different foods separate from each other, and you’ll have space for sauces and condiments as well. But if your kids prefer larger portions of fewer foods, you won’t need as many sections. While it might look cute to keep carrots separate from celery, having larger spaces will make it easier to pack lunch.
FAQs
What is a bento box?
Bento boxes are a type of lunch box that originated in Japan. They're designed to hold a single serving of food, and they're segmented into several compartments, typically to hold the main entree, along with one or multiple snacks.
Are bento boxes insulated?
Certain bento boxes, such as the OmieBox Bento Box, offer insulation that will keep your food warm until lunchtime, but the majority do not. Bento boxes are most commonly used to transport cold dishes such as sandwiches, and if you're packing a dish that must be warmed up, it's generally a good idea to pack it separately—otherwise, you'll have to take it out of the bento box to microwave it.
Can bento boxes be microwaved?
Some bento boxes are microwave-safe, but it's not a given, so you'll want to carefully review the product description before heating the container. Bento boxes made from metal or certain types of plastic should not be put in the microwave.
How do you keep food cold in a bento box?
For safety purposes, it's recommended that you keep lunch foods cold until you're ready to eat them, but this can be tricky with a bento box, as they're generally not large enough to hold an ice pack and rarely come with a space for one. The most common way to keep food in a bento box cold is to place the whole bento box into a larger lunch box along with an ice pack (or two).
