    Safermeal Bento Lunch Box Kit

    Bento Lunch Box Set | Eco-Friendly, BPA Free, Leakproof Container & Airtight Lid | For Healthy, Dry & Liquid Food, Portion Control, Meal Prep, Adults & Kids | Includes Spoon & lunch bag | By SaferMeal

    This is a great, compact lunch box which can fit pretty much anywhere. It’s one of the most portable lunch boxes on this list, albeit it is a tad on the smaller size. In addition to this, it offers a 30 day money back guarantee.

    This means you can buy the lunch box, use it for 30 days, and then decide if you like it or not.


    • The box is made out of high-quality BPA frree plastic. This means that it’s generally much safer for your health and more eco-friendly than other boxes. In addition to that, the PEVA lining which makes up the insulation of the box is also very safe and ecologically friendly.

    • It features 4 compartments, which is a great number for such a compact box. While there are multiple boxes on this list with a greater amount of compartments, this one has an excellent balance given its size.

    • The Bento is entirely leakproof and spillproof. The lid of this lunch box is airtight, which helps prevent any spilling or similar from happening. If you’re prioritizing leakproofing, then this is one of the better boxes on this list.

    • It’s very compact- the Bento can fit into pretty much any backpack, including your kid’s school backpack. This is great because it can help you take your meal anywhere without having to worry about how to pack your bag. 


    • The insulation of the box isn’t the best. While this is to be expected of such a compact box, don’t expect it to keep your food at the same temperature for more than half a day.

    • Because of being so compact, the box can also be a bit too small for some. Mostly because it doesn’t really carry enough to pack a full meal for someone that works a physical labour intensive job.

    Kids Basix New Wave Stainless Steel Snacker

    Kid Basix Safe Snacker Stainless Steel Lunchbox Container with Attached Lid, Lime, Large

    The Kid Basix is made with children in mind, although it can be of great help for adults. The box has a sleek, grey design with a colored lid. This helps it not stand out too much, while still maintaining a good visual identity.


    • It’s entirely leak-proof. This box featuresan 18/8 food grade stainless stell base, alongside a plastic lid with an insulated sillicone seal. This helps it lock in freshness, as well as any spillages that might occur inside.

    • The Kid Basix comes in three sizes. This is great because it lets you pick which one you want based on your food intake. The small or middle size will be great for your kid, while the biggest one is pretty much enough to feed the average adult.

    • Washing lunch boxes can be a pain, but luckily the Kid Basix is made to be 100% dishwasher safe, meaning that when you’re done with it you can just put it in the washer and forget about it.


    • While it does come in multiple sizes, all of these have only one compartment, which can be a significant downside to some. If you’re planning on storing multiple kinds of food in the lunch box, you might want to sleep on this one.

    Vaya Tyffyn 33.5 oz, Dew, Vacuum Insulated Lunch Box with Bagmat

    The Vaya Tyffyn is beauty incarnate. It’s probably the most beautiful of all the lunch boxes here. The sleek, segmented design goes with pretty much anything, and it oozes an air of quality(which it has in spades.)


    • The Vaya Tyffyn is made to keep food warm for up to 5 hours, and does this by using multiple vacuum-insulated compartments. This is one of the few boxes on this list that underestimates itself, as many users report it lasting for upwards of 7 hours.

    • The box is made up of 3 containers, which are then segmented into 2 parts, totalling 6 compartments. This means you can carry up to 6 different kinds of food init without facing any mixing. These containers are also entirely spillproof. The box is also dishwasher safe, so you can always just put it there when you’re done.

    • The box also carries a 1 year warranty with it. It’s common for well-designed products like these to have flaws when it comes to durability, but the Vaya Tyffyn seems to be facing no such issues.


    • If you don’t have a dishwasher, or use it rarely, then this box might be a pain to wash, as washing 6 containers by hand can take quite a while.

    MAZFORCE Original Lunch Box Insulated Lunch Bag - Tough & Spacious Adult Lunchbox to Seize Your Day

    MAZFORCE Original Lunch Box Insulated Lunch Bag - Tough & Spacious Adult Lunchbox to Seize Your Day (Wolf Grey - Lunch Bags Designed in California for Men, Adults, Women)

    The MAZFORCE lunch bag has been designed primarily with men in mind. It shows this with its strong, grey design, together with excellent functionality.

    It has multiple compartments to ensure that you bring everything with you, as well as a slot for your drinks on the side.


    • It has excellent insulation, due to not just the ultra-thick foam insulation, but also the outside cloth being an excellent insulator. This ensures that your food will be kept at a constant temperature during the daily grind.

    • The bag is extremely practical. Not a single inch of space has been wasted, the bag is designed to give it the maximum efficiency possible in such a size. There’s two mesh pockets, as well as a slim back pocket which will let you have some room for snacks.

    • The box is made from BPA and PVC free plastics, and has undergone a variety of safety tests to ensure that it is not only eco friendly, but also food friendly. Furthermore, the company offers a hassle-free guarantee for any dissatisfied customers.


    • The biggest downside of this bag is its cloth outsides. If you spill anything on top of it, you can expect it to be a fairly difficult stain to get rid of.

    Insulated Lunch Box for Adults and Kids - Professional Work Lunch Bag for Men and Women

    Insulated Lunch Bag with Water Bottle Holder - Girls and Boys School Lunch Boxes for Teen Boys and Girls -Kids Insulated Lunch Bag | Teen Lunch Box for Teenagers

    This bag is very much like the MAZFORCE, in fact, when it comes to functionality, their designs are pretty much the same. On the other hand, this bag has placed more of an accent on girls and children, rather than a manly, pure grey design.


    •  It is made of top-quality eco friendly materials. This ensures that the lunch box is quite durable, and can take quite a beating during the day.

    • It has waterproof, oxford fabric which provides an excellent appearance, and fixes the MAZFORCE’s greatest flaw-the outside. The outside of this box is extremely easy to clean, and you can easily do it with a wet wipe.

    • The thick, two-component insulation system makes sure that your lunch will maintain its temperature for much longer than it would with most other bags. In fact, some customers have reported upwards of 7 hours, while most seem to gravitate to a more modest 5-6.

    • It has a great size, while it isn’t too big to fit into a backpack, it’s not too small as to be unable to keep all of the food you need for a working day within it. It also features an expandable bottle holder, which can help carry your drink with you.


    • It’s not very good for carrying multiple kinds of food. This is because it relies on mesh compartments, so if you’re carrying, say, soup, you’ll probably want to avoid using those so the rest of your food doesn’t get wet.

    Lille Home 32OZ Vacuum Insulated Stackable Stainless Steel Thermal Lunch box

    Lille Home Vacuum Insulated Stackable Stainless Steel Thermal Lunch/Snack box, 2-Tier Bento /Food Container with Lunch bag, Smart Diet, Weight Control, 32 Ounces, Blue

    The Little Home has a great, gender-neutral design. If you’re looking for a lunchbox for the whole family, then this might be the one. It also comes with a convenient guarantee, so if you’re dissatisfied with the lunchbox, then you should just shoot the company an email and get a hassle-free refund.


    •  It offers one of the best temperature isolations on this list. It maintains the temperature pretty much perfectly up to 6 hours. After that, it’ll still maintain an “acceptable” temperature for a few more hours. If you’re looking for a lunchbox that can truly last you the whole day, then you need look no further.

    • The company is very transparent about the building materials. Both the interior and exterior are made from rustless SS304 steel, which is BPA free and retains no flavor or scent. It’s also very easy to hand-wash.

    • The bag is entirely spill and leak-proof. Every one of its stackable compartments comes with heavy-duty sillicone seals which help lock in any fluids which might otherwise excape.

    • It features multiple compartments, which lets you keep a variety of foods within it without them mixing. This is great if you’re thinking of bringing one lunch box to say, a family picnic.


    • The cylindrical design isn’t very space-economic in a backpack, so if you carry a small one you might want to sleep on this one.

    • It’s not made to be washed in a dishwasher. Luckily, it’s very easy to wash by hand, although this might present an issue to some customers.

    Pedeco Stainless Steel Divided Bento Boxes Leakproof BPA Free Lunch Box with 3 Compartments

    PEDECO Stainless Steel Divided Lunch Box BPA Free Metal Bento Box with 4 Divided Food Compartments for Adults or Kids Meal Prep Storage

    The Pedeco is made with function in mind first, however, it still maintains an excellent design. This is an excellent lunch box to get if you’re looking for a lunch box that has excellent function, while still maintaining an artistic style.


    • The box has 3 relatively sizeable compartments. Given its compact size, this is a great thing, because it lets you have a balanced and nutritious meal, rather than being forced to bring just one sort of food.

    • It’s got probably the best leakproofing of all the boxes so far. There’s a silicone sealing ring you can put on all three of the compartments. This means that the innate leakproofing of the box is completmented with an additional layer of protection.
    • The box is very easy to clean due to being pretty much all stainless steel. All three compartments are removable, which makes washing super easy.  You can also remove the metal parts of the compartments and make the box microwaveable. 


    • It’s on the small side. This is to say it doesn’t exactly let you carry a full meal if you eat a bit more than the average person.

    Carhartt Insulated Soft-Sided Lunchbox

    Carhartt Insulated Soft-Sided Lunchbox, Carhartt Brown

    The Carhartt is a simple, yet well made bag. While its design isn’t the most exciting one ever, it goes great with certain outfits. Furthermore, it really helps complete the “image” of some professions, such as lumberjacking.


    • It’s great for both kids and adults. The soft-sided insulated design makes sure that your kids won’t hurt themselves in case they fall on it, or it falls on them.

    • It features a fully insulated interior, which is designed to keep your food fresh from when you leave your house until lunchtime. This can often be for time periods longer than 6 hours, which makes this bag an excellent pick for keeping your food fresh until you’re ready to eat.

    • It has a sturdy handle at the top of it, which makes it a great option in case you don’t always take your backpack with you. It also makes transporting it easier without having to put it back into your backpack.

    • It uses very durable synthetic fabrics with Rain Defender to make sure that it’ll withstand rugged use. Furthermore, if you spill something on the bag you needn’t worry because of the material’s hydrophobic properties.


    • It’s a bit too big for most backpacks, if you’re looking for a bag to fit into your kid’s school backpack, then you might be better off looking at a different bag.

    • It doesn’t have many insulated areas. With only a main pocket and a mesh pocket, this isn’t the ideal lunch bag to carry with you if you’re looking for a varied meal.

    • Its design is superb, this is perfect for those of us that are a bit more eccentric, or for children looking to have fun at school. With that being said, it can be a bit “much” for a professional environment.

    • It’s made of 100% polyester, meaning it’s extremely food friendly and eco friendly. The bag won’t be retaining any kind of scent or taste from the food you put in it.

    • The box is deceptively large, being able to house an entire adult’s meal with ease. Furthermore, for such a large bag, it’s extremely good at laying flat, which means you can easily use it as a tray if need be.

    What to Consider When a Lunch Box For Your Backpack


    You always want to think not only about how much stuff you can fit in your lunch box, but also how many ways you can arrange it. You don’t want to keep all of your sauces in the same place as the rest of your food if you can help it.

    You also don’t want your drinks to be spilling out into your food, so you should make sure that they’re kept in different compartments. Things like these are why you should be thinking about the number of compartments.


    The Design of your lunch box is always important. You might be thinking “what’s the point if I’ll just keep it in my backpack anyways?”

    Well, while this is true, you’ll still take it out when you eat. You want the design of your lunchbox to go with you, rather than going against the rest of your outfit.


    Picture this: you open your backpack after working for a while. You’re stressed out because of one thing or another and you find that your drink has spilled into your backpack and ruined it.

    To prevent this kind of thing from happening,  we’ll be looking at the leakproofing of these lunch boxes.


    If you didn’t care about the portability of your lunch box you might as well take your fridge with you. The less you have to carry in your backpack, the better. Portability isn’t only size, however, as the shape of a lunch box can also alter its portability.

    We’ll also pay a passing glance to whether or not the lunch box is practical in case your backpack is out of commision for whatever reason.


    Do you want to buy a new lunch box every two months? Unless you’ve got some kind ofstrange fixation on buying lunch boxes, you probably don’t. This is why you want a lunch box that can take a bit of damage.

    It’s inevitable that your lunch box will end up falling here and there, and you don’t want it breaking when that happens.


    The same way you don’t want your lunch box to break, you don’t want it to break the bank either. What you’ll be looking for is mostly value for your money. You want to get as much preformance out of the lunch box for as little money. 


    If you’re going to put your lunch box in your backpack, common logic dictates it needs to be smaller than said backpack for this to work. Naturally, you also don’t want it to be so small you can’t fit your lunch in it.

    Depending on how much you eat, the Goldilocks zone for your lunch box is going to be different, but we’re here to tell you how big the box is at least.


    Finally, one of the most important things to consider when getting a lunch box is whether or not it has the capability to keep your food warm/cold depending on the way you want it to be.

    If you packed up ice cream, you don’t want it to melt, and if you packed warm soup, you don’t want it going cold either.
