A lunch box with a separate insulated food jar can make it easier to pack warm soup, pasta, or oatmeal alongside fruit and other cold foods. The best fit depends on your child’s appetite, how much help they need opening containers, and how much cleanup you want to handle after school. These five picks range from all-in-one bento sets to a box with a removable stainless steel jar; two listings were marked unavailable in the supplied product information, so check their current status before choosing one.

FAJSL Game Bento Box: A Playful Set With Handy Extras
The FAJSL set pairs a multi-compartment bento box with a 9-ounce stainless steel insulated food jar. It also includes a folding stainless steel spoon, a sauce cup, and removable dividers. The raised buttons and game-inspired shape give it a more distinctive look than a plain, flat lunch box.
The removable dividers let you adjust the space for sandwiches, fruit, snacks, or a fuller meal. A separate sauce cup helps keep dips apart from the rest of the food, while the jar’s lid has a spot for the folding spoon. The jar also has a vent button, which the product description says helps prevent pressure buildup and makes opening easier.
This is a practical pick if your child likes variety and you want several lunch accessories in one set. The 9-ounce jar is a modest portion, so it may work better for a side of soup or oatmeal than for a large main meal. The playful shape and extra pieces may also mean more parts to keep track of and clean.
Pros:
- Includes a 9-ounce stainless steel insulated food jar and folding spoon
- Removable dividers make it easier to arrange different foods
- Separate sauce cup helps keep dips contained
- Product information states the bento box and jar are dishwasher safe
Cons:
- The jar may be small for a child who needs a large hot-food serving
- The set has several small accessories that can be misplaced
Verdict: Choose the FAJSL if a fun design, adjustable compartments, and a spoon stored with the food jar matter more to you than a larger thermos.
WXXM Kids Bento Box: A Four-Compartment Set With a Carrying Bag
The WXXM set combines a four-compartment bento box, a 9-ounce soup thermo, and an insulated lunch bag with a built-in handle. Its description says the sealed compartments keep foods separate, while the vacuum-insulated jar is designed to keep soup, pasta, and other meals warm for hours.
The included bag is a useful distinction from sets that provide a bento box and jar but no carrying case. Four compartments can help you pack several foods without mixing them together. The product is described as BPA-free and made with food-grade stainless steel, though the available information does not specify whether the bento box is dishwasher safe.
The main caution is that this listing was marked unavailable in the supplied product information. If it becomes available, confirm the listing details before buying, including the included bag and the current product options. The 9-ounce jar may also be too small for a child who prefers a larger serving of soup or pasta.
Pros:
- Includes a 9-ounce soup thermo and insulated carrying bag
- Four compartments are intended to keep foods separate
- Product description says the jar keeps meals warm for hours
- Bag has a built-in handle for carrying
Cons:
- Listing was marked unavailable in the supplied product information
- Jar capacity may not suit larger portions
Verdict: The WXXM is worth considering if you want a lunch bag included with a four-compartment box, but check that the listing is available and confirm its details first.
Pawtong Bento Lunch Box: Simple Latches and a Compact Soup Jar
Pawtong’s set includes a bento box with four sealed compartments and an 8-ounce vacuum-insulated soup thermo. It uses a single lock buckle on the lunch box and a latch design on the jar, with the goal of making both easier for children to open.
The compartments are intended to limit leaks and keep foods from picking up each other’s flavors. The product information says the lunch box is microwave safe and dishwasher safe, and that the sealing rings on both the box and jar can be removed for cleaning. The wide-mouth jar is another practical touch for filling and washing it.
Pawtong recommends warming or cooling the jar with hot or ice water for five to ten minutes before filling it, to help food stay hot or cold longer. That extra preparation may be a drawback on rushed mornings. Its 8-ounce capacity is smaller than the 9-ounce jars in several other picks, but the simple closures may suit younger children who find more complex lids frustrating.
Pros:
- Four sealed compartments help keep foods separate
- Product information describes the box as microwave safe and dishwasher safe
- Removable sealing rings and a wide-mouth jar make cleaning more manageable
- Simple buckle and latch designs are intended to be child-friendly
Cons:
- The 8-ounce jar is smaller than the 9-ounce options here
- Preheating or precooling the jar takes additional time
Verdict: Pick Pawtong if easy-to-clean seals and straightforward closures are priorities, and an 8-ounce jar is enough for your child’s hot-food portion.
Omie OmieBox: A Built-In Jar for Hot and Cold Foods
The OmieBox is designed to carry warm food alongside cold items in one organized lunch box. Its removable 18/8 304-grade stainless steel vacuum-insulated container sits within the bento layout, so you can pack a warm entree with fruit or vegetables instead of relying on a room-temperature meal.
The product description highlights removable seals and dividers, along with replaceable parts such as seals and dividers. That design can be useful for thorough cleaning and for extending the life of the box if a part wears out. The listed age grade is 3 years and up, and the box weighs 1.7 pounds, which is worth considering for a young child’s backpack.
The listing was marked unavailable in the supplied product information, so check its current status before planning to buy it. Its weight is also higher than the 1.3-pound BEAQUEE set, and there is no jar capacity listed in the supplied details. Take care when packing hot food, as the product description cautions about handling hot water and food.
Pros:
- Built-in layout is designed for packing hot and cold foods together
- Removable stainless steel insulated container
- Seals and dividers can be removed for cleaning
- Replaceable parts can help avoid replacing the entire lunch box when a component wears out
Cons:
- Listing was marked unavailable in the supplied product information
- At 1.7 pounds, it is a relatively substantial item for a child’s backpack
Verdict: The OmieBox stands out for packing hot and cold foods in one container, but its listed weight and unavailable status make it important to check the current listing before deciding.
BEAQUEE Bento Box: A Lightweight Set With a Spoon and Sauce Cup
The BEAQUEE set includes a bento box, a 9-ounce insulated food jar, a silicone sauce cup, a stainless steel spoon, and removable dividers. Its three-compartment layout can be adjusted for different foods, while the jar is made from 18/8 stainless steel and has a wide mouth for filling and eating.
The lid has a spoon holder, and the product description says the lunch box is designed so the handle and locking clip are on the same side to make opening easier for kids. The set is listed at 1.3 pounds, lighter than the OmieBox described above. It is intended for children ages 3 and up and is presented as an all-in-one option that does not require an extra lunch bag.
The sauce cup is described as leak-resistant, but that is not the same as a guarantee that the entire box is leakproof. The product information says the accessories are dishwasher safe; it does not clearly state that the bento box itself is dishwasher safe. If cleaning the box in a dishwasher is important, verify that detail before buying.
Pros:
- Includes a 9-ounce jar, stainless steel spoon, and silicone sauce cup
- Removable dividers allow changes to the three-compartment layout
- Wide-mouth stainless steel jar is designed for easier filling and eating
- Listed weight of 1.3 pounds is lighter than the OmieBox’s listed weight
Cons:
- The supplied details do not clearly state whether the bento box itself is dishwasher safe
- The sauce cup is described as leak-resistant, not the whole lunch box
Verdict: Choose BEAQUEE if you want a relatively light set with an included spoon, sauce cup, and adjustable compartments, and you do not need a confirmed leakproof claim for the full box.
How to Choose a Lunch Box With a Thermos for Kids
Match the Jar Size to Your Child’s Appetite
The food jars in these sets range from 8 to 9 ounces, while the OmieBox listing does not provide a capacity in the supplied details. Think about whether the jar will hold a small side of soup or a main serving of pasta or oatmeal. If you are unsure, measure a portion your child already eats at home and compare it with the jar’s stated capacity.
Decide How You Want to Separate Hot and Cold Foods
Some sets pair a separate insulated jar with a bento box, while the OmieBox is designed to fit its removable insulated container into the lunch box. A separate jar gives you more flexibility to pack the rest of the meal in the bento compartments. An integrated layout may be simpler if you want warm food and cold sides together in one organized container.
Check Closures and Portion Layout
Consider how easily your child can open the box and jar without help. Pawtong highlights a single buckle and a jar latch, while BEAQUEE places the handle and locking clip on the same side. Compartment count matters too: four sections can make it easier to pack several small foods, while removable dividers let you adjust the size of portions.
Look Closely at Leak and Separation Claims
Product descriptions use different wording for leak protection. WXXM describes four sealed compartments, Pawtong says its compartments are sealed to prevent leakage, and BEAQUEE describes its sauce cup as leak-resistant. Those claims apply to specific parts of each set, so do not assume they mean every part of the lunch box is leakproof. For saucy foods, check the product details carefully and pack the box upright when possible.
Plan for Cleaning and Replacement Parts
Removable seals and wide-mouth jars can make it easier to clean hard-to-reach areas. Pawtong says its sealing rings are detachable, and Omie describes removable seals and replaceable parts. Dishwasher instructions differ across these products, so confirm which pieces can go in the dishwasher rather than assuming the whole set is dishwasher safe.
Consider What Comes in the Set
A spoon, sauce cup, dividers, or insulated bag can reduce the number of extra items you need to pack. WXXM includes a carrying bag; FAJSL and BEAQUEE include spoons and sauce cups; and Pawtong focuses on the lunch box and jar. Compare the included accessories with what your child already uses so you do not end up carrying unnecessary pieces.
Think About Weight and Everyday Carrying
A lunch set adds weight before you add food. The supplied details list the BEAQUEE set at 1.3 pounds and the OmieBox at 1.7 pounds. The other products do not provide a weight in the information available here. If your child carries a small backpack, consider the set’s weight, size, and whether it needs a separate bag.
Frequently Asked Questions
Can these lunch boxes keep food warm until lunchtime?
The food jars are insulated, and the WXXM description says its vacuum-insulated jar keeps meals warm for hours. Actual results can depend on the food, starting temperature, and handling. Pawtong recommends preheating its jar with hot water for five to ten minutes before filling it to help food stay hot longer.
Which option has the largest listed food jar?
WXXM, FAJSL, and BEAQUEE list 9-ounce jars. Pawtong lists an 8-ounce jar. The supplied OmieBox details do not state the jar’s capacity.
Are the bento boxes microwave safe?
Pawtong’s product description says its lunch box is microwave safe. The supplied information does not make the same claim for the other bento boxes. Check the manufacturer’s instructions for each item before putting any part in a microwave.
Can I put these lunch sets in the dishwasher?
FAJSL says its bento box and food jar are dishwasher safe, and Pawtong says its lunch box and jar are dishwasher safe. BEAQUEE says its accessories are dishwasher safe, but the supplied details do not clearly confirm dishwasher use for the bento box itself. Check the care instructions for every component, including seals and lids.
Which set includes a carrying bag?
WXXM is the set that specifically lists an insulated lunch bag with a built-in handle. BEAQUEE says its set does not require an extra lunch bag, but it does not list a separate carrying bag among the included items.
Are all of these lunch boxes leakproof?
No. The product descriptions make different claims about different parts. Omie is described as leakproof, while WXXM and Pawtong describe sealed compartments. BEAQUEE calls its sauce cup leak-resistant. FAJSL’s description highlights a sauce cup that keeps sauce separate, but does not describe the full lunch box as leakproof.
Which lunch box is best for a younger child?
Pawtong and BEAQUEE both describe features intended to make their sets easier for children to open. Omie lists an age grade of 3 years and up, and BEAQUEE also specifies ages 3 and up. A child’s ability to open the closures independently is still worth checking before school use.
Final Recommendation
For a flexible all-in-one set with a 9-ounce jar, spoon, and sauce cup, the FAJSL is a strong place to start. Choose Pawtong if easy-to-clean seals and child-friendly closures matter most, or BEAQUEE if you want a relatively light set with several useful accessories. WXXM and Omie have distinct features, but both were marked unavailable in the supplied product information, so confirm their current listing status before making plans to buy either one.
