Omie bento box

The Spruce Eats / Brigitt Earley

When your kids leave for school in the morning, you probably ensure they have a few essentials: backpack, homework, etc. No matter how old your children are—preschool or high school—chances are you send them off most days with a lunch box packed with their favorite foods.

While the best lunch box for your kid likely depends on their age, style preference, and the type of lunch they normally eat, we tested some of the top-rated options to help you decide. We put some top-rated selections to the test in our home kitchens, packed dozens of lunches and toted the lunch boxes around. Then, each lunch box was rated on design, versatility, insulation, size, and overall value.

What We Like
  • Leakproof design

  • Rubber sides are extra durable

  • Easy to clean

  • Comes in lots of fun colors

What We Don't Like
  • Slightly heavier than other models

  • Exterior scratches pretty easily

Bento boxes are a popular choice for children, as they allow you to separate food and snacks in various compartments, and one of the best products you’ll find today is the popular Bentgo Kids' Lunch Box. Designed with kids in mind, this lunch box comes in three bright colors, and it features five compartments that are perfectly portioned for kids ages 3 to 7. After testing, this one earned our best overall spot—approved by both parent and kid testers.

This bento box has drop-proof rubber-coated edges in case it takes a tumble, and it opens and closes using two kid-friendly latches. The inner compartments are different shapes to hold a variety of food and snacks—even dipping sauce!—and there are seals to keep the contents from leaking into your child’s backpack. The inner tray can be put in the microwave and dishwasher, and the box is made from BPA-free materials.

We particularly loved its solid build, well-designed compartments, and the fact that it was truly leakproof when put to the test in a backpack. The rubberized seal all around the perimeter of the lunch box is effective in preventing this spillage or mess, both between compartments and out of the box itself.

What We Like
  • Affordable pricing

  • Fits Rubbermaid or Tupperware containers

  • Features bottle holder and utensil compartment

What We Don't Like
  • Limited insulation

  • Requires additional packaging

This budget-friendly lunch bag is perfect for children in elementary school. This won't break the bank, but it's also surprisingly spacious and perfect for school lunches. This lunch bag comes in four colorful designs, including blue, purple, and black patterns.

With testing, we found this bag to be extremely lightweight, even when packed with an array of favorite foods. If there’s any downside, it is that you need to package all of the food in a separate container—this lunch box is simply an insulated bag. It’s designed to be used with Rubbermaid LunchBlox food containers, but you can also use it with whatever Tupperware or bento box you have at home, which keeps things flexible regardless.

We also loved that it has a side zip closure that wraps around the entire thing, making it easy to pack and unpack. There are also mesh pockets on either side where you can store additional food. This lunch box is safe for the microwave, dishwasher, and freezer. It's also BPA-free.

What We Like
  • Gel liner can replace ice packs

  • Spacious interior

  • Collapsible for easy storage

What We Don't Like
  • Bottle pocket is small

  • Heavy, especially when frozen

Who needs ice packs when you have a freezable lunch box? The unique PackIt Freezable Lunch Box has freezable gel built into its walls, so all you have to do is pop it into the freezer the night before, and in the morning, it will be ready to use. In tests, the frozen walls were highly effective at keeping food insulated and fresh for longer—we didn't have to use any ice packs, even for food like yogurt.

This lunch box comes in a wide range of fun patterns to appeal to children, and it’s large enough to fit a sandwich, snack, and 12-ounce drink. We never wanted for more space, even when packing for little ones with hefty appetites. There is a zip pocket and a mesh pouch on the exterior of the bag, and the whole thing is made from canvas with a water-resistant lining, so we found it easy to wipe clean.

If there’s any downside, it’s that it was relatively heavy—even when not frozen—making it difficult for smaller children to comfortably tote on their own.

What We Like
  • Comprehensive lunch set

  • Range of colorful patterns

  • Dishwasher-safe containers

What We Don't Like
  • Containers can be hard to open

  • Relatively heavy when fully utilized

The Bentology Lunch Bag and Box set comes with everything you need to pack a delicious meal for your kids. The set includes an insulated lunch bag, a plastic bento box, a five-piece set of containers with leak-proof lids, and a matching ice pack, and you can choose from a dozen bright, colorful patterns to suit your child’s style.

This affordable set is made from BPA-free materials, and the lidded containers can go in both the microwave and dishwasher—something we found to be key for simplifying lunch prep and cleanup. You can mix and match the containers inside the bento box for versatility, and it all fits inside the insulated lunch box for easy packing. There’s even a mesh pocket on the side of the bag where you can slip a water bottle for your kids.

In tests, food stayed fresh for a long time—even without the extra ice pack. There was one sacrifice to be made for these conveniences, though: we found the lunch box might be a bit heavy for younger children to be carrying around.

What We Like
  • Kid-friendly colors and designs

  • Wide mouth is easy to eat from

  • Keeps food cold or warm

What We Don't Like
  • Hand wash recommended

  • Must be pre-heated for maximum heat retention

If your child likes to take soup to school for lunch, they’re definitely going to need a container like the Thermos Funtainer Kids Food Jar. The insulated jar can hold up to 10 ounces of food, and it comes in a variety of kid-friendly colors and patterns, including options with characters from popular shows like Paw Patrol and Frozen.

This thermos for kids has a wide mouth that’s easy to fill and eat from, and according to the manufacturer, it can keep food cold for up to seven hours or hot for up to five. When we tested this in our home kitchen, we found that it impressively lived up to those claims. Macaroni and cheese was hot enough to eat safely after five hours in the container, and ice was still present after seven hours. It has a durable stainless steel interior and exterior, and when closed, we found it was leakproof, preventing any lunch box spills.

The jar is technically top-rack dishwasher safe, but the brand recommends hand-washing to increase its longevity. We noted that hand-washing also helped clean out the nooks and crannies in the lid. We recommend going so far as removing the O-ring gasket to really get in there and prevent any mold issues down the line.

What We Like
  • Removable thermos for hot foods

  • Large compartment fits a sandwich

  • Can be fully disassembled for cleaning

What We Don't Like
  • Expensive

  • Must be hand-washed

If you're looking for a great segmented lunch box to send to school, look into the unique OmieBox Bento Box. Part of the reason bento boxes have become increasingly popular is because of all the different foods they can accommodate. This one features two temperature zones, which allow you to store both hot and cold foods in one box.

The OmieBox Bento Box comes in five bright colors, and it includes a built-in thermos food jar. This keeps entrees like soup warm until lunchtime. The lunch box itself is double-walled and leakproof, so you don't have to worry about spills, and its contents will stay cool and fresh.

We liked how securely it closed and that we didn't have to worry about spills (even with apple sauce packed in the thermos). Plus, it's easy for kids to carry thanks to the handle. The main downsides are that it doesn't come with utensils and it's a bit difficult to clean. Still, we think it's a quality bento box that we expect to last a long time.

What We Like
  • More than a dozen patterns

  • Insulated interior

  • Fits standard bento boxes

What We Don't Like
  • Light interior can get stained

  • Interior pocket doesn't have closure

Sending your little one off to school for the first time? Make sure they have everything they need to conquer preschool with the help of the Wildkin Lunch Box. This kid-friendly lunch box is designed for ages 3 to 15, and it comes in more than a dozen fun patterns to showcase your child’s personality. It's slim enough to fit inside a backpack-style diaper bag easily and light enough that little kids can carry it.

This insulated lunch box is spacious enough to accommodate a bento box or several plastic containers, and it includes a mesh pouch on the interior where you can tuck an ice pack, napkins, or utensils. We were able to fit half a PB&J, a fruit pouch, a cheese stick, a snack pouch, and a water bottle—with room to spare. Plus, at the end of the day, you can simply wipe down the interior with a washcloth, and it will be ready to go again the next morning. We found there were no lingering odors, either.

There’s a zippered front pocket where you can hide an encouraging note for your preschooler, and the insulated interior helps maintain a hot or cold temperature to ensure their food is always fresh. We found that without an ice pack, food stayed cool for one to two hours, but with an ice pack, food can stay cold for four to five hours.

How We Tested

We tried out more than a dozen lunch boxes and packed a variety of food items—everything from sandwiches and salads to fruit, yogurt, smoothies, and snacks—and rated each lunch box on its design, insulation, versatility, size, and overall value. We then provided additional insights on how easy the lunch boxes were to clean, whether anything leaked and if food stayed separated in compartments, and what kids thought, too!

Other Options We Tested

  • Opux Insulated Dual Compartment Lunch Bag: This spacious lunch bag has a "dual deck" design that is more suited for older children or adults. The bottom section is insulated and leakproof, making it ideal for cold food and drinks, and it’s large enough to fit up to 10 cans. The top section is great for snacks and other items you might need to grab quickly, and both compartments have reinforced zippers for durability. There are also two side mesh pockets for water bottles, as well as two front pockets for utensils or other small items. Our tester reported that it is well insulated and has a lot of usable compartments, but ultimately decided it's too big and bulky for kids. "I think this lunch box is much too large for children. It's really more of a mini cooler. You could pack a full day's worth of food in here for one person," she reported.
  • LunchBots Large Trio Stainless Steel Lunch Container: This is a bento-style, durable metal option that features a three-compartment design. Our tester found the compartments to be roomy enough for a wide range of foods. There’s one large section that can hold a sandwich, as well as two smaller areas where you can pack snacks and even smaller whole fruits, like clementines. It worked well for keeping delicate sides and snacks, like berries or pretzels, separate and intact. However, it's expensive for a lunch box, and it doesn't provide any real insulation. It also doesn't have room for a drink, and the compartments are fixed. As a result, it's not super versatile. Plus, it doesn't have a handle for carrying. This is a long-lasting bento box that would definitely work for some people, but we decided it's not necessarily the best lunch box for kids—particularly given the price.

What to Look for in a Lunch Box for Kids

Size

The age of your children and what they like to eat for lunch will determine how big a lunch box they need. Young children in kindergarten or preschool may be fine with small bento boxes that just hold half a sandwich, but older children may need a larger lunch box that can hold a full-size entree, multiple snacks, or a water bottle. Keep weight in mind as well, as your child will have to carry the box around in their backpack.

Design and Accessibility 

If you’re buying a lunch box for young children, you’ll want to consider whether they’ll be able to easily open all its components. Some lunch boxes are tricky clasps that small fingers can’t manage, and some hot food containers have to be screwed on tightly to prevent leaking—these types of issues can make it frustrating for your child to get to their food.

Insulation

A lunch box with good insulation is key to keeping food safe until lunchtime. You’ll likely end up putting ice packs into it—though some lunch boxes have built-in gel linings—but the ice can melt quickly if the container doesn’t have enough insulation. On the flip side, kids who take hot lunches will need a thermos or other insulated container that can keep food warm for several hours.

FAQs

What is a bento lunch box? 

Bento boxes originated in Japan, and they’re designed to hold a single serving of food, including a main dish and several sides. These lunch boxes are divided up into multiple compartments—commonly between three and five—and they have a compact form that’s easy to transport in a backpack or other bag. 

How do you wash a lunch box?

At the end of each day, you should wash your child’s lunch box using warm, soapy water, making sure to get into any cracks and crevices. You can then let it air dry. Alternatively, some lunch boxes can be placed in the dishwasher, allowing for hands-free cleaning.
