Best Stainless Steel Box for Toddlers and Kids Reviews

1. Best Overall: LunchBots Cinco Bento

LunchBots Cinco Bento is a fairly large stainless steel lunch box. In fact, it is 60% bigger than most LunchBosts classic containers.

It is made of high-quality, durable 18/8 stainless steel and contains no plastic whatsoever, making it suitable for packing healthy meals for mischievous kids.

Its huge size allows you to pack up all sorts of fruits, vegetables, salads, protein, and snacks to make lunch fun and exciting for your kids.

It features an all-in-one design that keeps food separated neatly into 5 different compartments. So you don’t have to pack food in several smaller containers. 

The sections allow you to separate your child’s favorite fried chicken from berries to avoid different types of foods from becoming soggy and mixed-up.

The fun part of this container apart from its five sections is that you can customize its cover for your kids with different snap-on colored dot covers, which include aqua, blue, green and pink. You can also buy one without the colored tops.

Since the container is virtually indestructible, it’s great for an on-the-go lifestyle and can last for a long time.

However, one key caveat of this container is that you can’t put juicy or liquidy foods like soup or salad with dressing in it since there’s a small gap between the divider and the bottom of the container that may cause the liquid to migrate from one section to another.


  • Has five sections
  • Durable and safe
  • Trusted brand
  • BPA-free
  • Free of toxins and chemical linings
  • Eco-friendly
  • Dishwasher-safe
  • Freezer and refrigerator-safe


  • Lids and dividers aren’t watertight so be sure to pack only dry foods
  • Non-microwavable 

2. Best Runner-Up: PlanetBox ROVER Lunch Box

PlanetBox Rover is one of the most popular stainless steel food containers amongst parents since it is a whole lunch box system.

For every Rover set, you get 1 stainless steel lunch box, 1 big and 1 small dipper food container with a silicone cover, insulated carry bag and magnet sticker.

The durable carry bag is made of 100% recycled polyester fiber and comes in a variety of colors and patterns. It has an adjustable nylon strap, so you can adjust the strap’s length according to your preference. 

Since the bag’s main compartments are wipeable, you can easily wipe it with napkins or wet tissue when dirty.

The bag’s front side has 1 open compartment for a water bottle, and 1 velcro-stripped pocket with a wipeable surface where you put your snacks, utensils, or other items (even your kids’ diaper!).

The carry bag comes with big zippers that kids can open with ease. When opened, the bag reveals another compartment and elastic straps for utensils or other items, along with the stainless steel lunch container.

The stainless steel lunchbox features 5 compartments with 4 main compartments and 1 special treat spot.

Another fun feature of this container is that you can customize your kids’ lunch box with their favorite magnetic stickers.

The containers are made of 304 food-grade stainless steel, BPA-free, and PVC-free, making it a safe and practical food container for both kids and adults.

One large DaCool container can fit 5 smaller containers:

  • 2 of the 5 containers have a capacity of 9.08 oz, which can fit large food items, such as the main course, meat, large fruits, salad, vegetables, sandwiches, and many more.
  • 3 of the 5 containers have a capacity of 4.7 oz, which can hold smaller-sized food items like small fruits, yogurt, nuts, cake, candy, and other tasty snacks.

All inner containers feature a safety feature of double lids with a seal ring to prevent any leakage. In addition, the large or outer container’s lid has 4 clip-ons on all sides for a more secure and tight seal.

The lids are easy for kids to close and open.

The container also comes with a FREE insulated bag with a double zipper to keep your foods cold or warm much longer and one spork-spoon with a spork bag.

Another cool thing about this container is that the supplier, DaCool, offers lifetime customer service. So you can easily reach out to them if you encounter any issues with the container.

However, while the stainless steel containers seem to do well in the dishwasher, the lids may warp when placed in the dishwasher. 


  • Leakproof

  • Comes with a free insulated bag and spork


  • Lids are not dishwasher-safe

1 of the containers has 2 compartments, so you’ll get a total of 3 available compartments to keep your food.

The build of these containers is excellent; their interior is made of high-quality stainless steel, while their exterior is made of BPA-free, lead-free, paraben-free, food-grade plastic that is resistant to flavor and smell. This design allows your food to stay warm for a couple of hours.

The lids feature a silicone ring and a clip-on on each side for a safe, more secure, and leak-proof storage experience.

They also come with a BPA-free folding spoon and a removable silicone handle for easy carrying without the need for an additional lunch bag.

Their overall design is cute, allowing your child to carry their lunchbox with confidence.

One caveat of this lunch box is that it is not microwaveable.

  • Made of durable and tough material
  • Leak-proof
  • BPA-free
  • Comes with a free removable handle and a folding spoon

5. LunchBots Quad Stainless Steel Container

LunchBots Quad eco-friendly stainless steel container is made of high-quality 18/8 stainless steel, making it safe, durable, and long-lasting.

It has 4 compartments; all compartments have the same size.

With a dimension of about 15cm x 5cm x 4.5cm, some people may consider this container to be a little bit small for a lunch box. However, it is perfect as a snack box or lunch box for toddlers.

You can easily customize the container with your kids’ favorite colored tops. You can choose from blue dots, green dots, pink dots, purple dots, and royal blue dots. 

You can also buy the container without its colored top for a cheaper price.

It is easy to clean and dishwasher-safe. You can wash the dots cover without detaching it from the lid.

One key disadvantage of this container is that the dividers and lids are not watertight, so you can only pack dry foods like chopped fruits, sliced vegetables, and nuts.

Also, since it is made of metal (stainless-steel), it is non-microwaveable.


  • It is not leakproof
  • Not suitable for liquidy or juicy foods
  • Dishwasher-safe

6. WeeSprout Bento Box

You can safely store this freezer-safe stainless steel container in the freezer anytime there’s a leftover.

The container’s smooth design is easy to clean with no nooks and crannies and can be placed in the dishwasher (top rack).

7. OmieBox Bento

Unlike previous containers which are mostly made of stainless steel, OmieBox Bento is mostly made of high-quality, food-grade silicone with a built-in insulated, 18/8 stainless steel thermos.

The thermos can hold about 7.5 oz or 1 cup of hot foods or liquids and is removable. So you can remove it when not in use and use the free space to put other cold foods and insert it when you want to pack hot foods or liquids for your kids.

The container comes with 3 compartments: 1 long compartment that can fit any brand of box drinks, 1 compartment for thermos insert (which is removable), and another compartment to keep other food items.

The cool part of this container is that it comes with a divider, which you can use to customize and add an extra compartment to separate your food.

All compartments have their corresponding rubber seals, so each compartment stays tightly sealed when closed to make sure the food does not leak out when your kids carry it to school.

It is easy to clean because the rubber seals are removable. You can wash it thoroughly every day.

If the seals get worn out or damaged, you can buy replacement seals instead of throwing the container out.

One main caveat of this container is that there is no space for utensils (unless it is thin) if you fill-up the box with food. 

The container’s other disadvantage is that its removable divider is not exactly leak-proof. So you might want to avoid putting in food with juices or watery foods when you use the divider.

  • FDA and CPSIA compliant
  • Leakproof
  • Compartment is customizable
  • Can store hot food
  • Great design and has 3 vibrant color option that kids will love

  • The divider is not watertight 

8. Clean Lunch’N Metal Bento Box

You can put the container in the fridge or freezer to keep your food fresh and cool.

Clean Lunch’N also offers you the option to get its portable Insulated Lunch Bag that fits well with its lunch box and can keep your kids’ meal stay hot or cold all day long.

One caveat of this lunch box, however, is that it is not suitable for wet or watery foods since the dividers are not leak-proof. So their sauces will leak to other compartments and make the food soggy.

Buyer’s Guide: How to Choose the Right Stainless Steel Lunch Box for Toddlers and Kids

When searching for the right or best stainless steel lunch boxes for your kid online, you’ll easily get confused and overwhelmed with the various options available on the market.

Follow the tips below to help you pick the right stainless steel lunch boxes for your kids and toddlers.

Consider the container’s material and durability

Make sure the lunch box is made of high-quality, food-grade stainless steel which is durable and built to last.

Also, look for stainless boxes that are free of Bisphenol-A or BPA-free to ensure no harmful toxins will leak out of the container and contaminate your kids’ foods.

Consider your kids’ food storage needs

You need to pick a suitable container size depending on how much your kids usually eat or what kind of meal you typically prepare for your kids.

If your kids eat a lot and love eating a variety of food, then you should probably choose a large stainless steel food container that comes with several compartments.

Consider the container’s water-tight or leak-proof feature

If you often pack watery foods like sauces, soups or stew for your kids, then you should choose a lunch box that is spill-proof or leak-proof to make sure the food is sealed tightly inside the container and does not leak out and dirtied your kids’ bag.

Consider the container’s cleaning needs

You should buy a stainless steel lunch that is easy to clean or dishwasher-safe to save time and effort when cleaning. Certain containers can only be hand-washed but are still easy to clean.

Be sure to check out the manufacturer’s cleaning instructions, especially those that come with silicone or rubber seals. Some rubber or silicone seals are removable and dishwasher-safe while others not.

Containers with removable parts are easier to clean.

Consider the container’s style or design

Although the main purpose of buying a stainless steel lunch box is to store your kids’ meals or snacks, you should also pay attention to the container’s design. 

No matter how practical a lunch box is, your kids may not be willing to carry an old-fashioned, dull container.

So be sure to find one that has a cool or fun design and color that suit your kids’ fashion sense.

Can you microwave stainless steel lunch boxes?

Lunch boxes made of stainless steel, or any other metal, are non-microwaveable. In the microwave, stainless steel will prevent heat from warming the food or drink and act as a mirror that will reflect the microwave’s light waves, generating sparks and fire. The microwave may explode when not turned-off promptly.

Does a stainless steel lunch box keep food warm?

Ordinary stainless steel lunch boxes do not keep the food warm. But vacuum-sealed, insulated stainless steel containers like stainless steel thermos can keep your food cold or warm for several hours by preventing heat or cold from escaping without the help of a cooling or heating device, microwave, or electricity.
