OmieBox UP bento box for kids | Insulated lunch box

The box is compact, easy to open, and pretty sturdy. the plastic is very think and it seems big, but It fits perfectly in my kids' lunch boxes and isn't too bulky or heavy. The thermos works well, my kids have come home ever since they started eating from the box saying that their food was warm. Minimal but just enough storage for a small meal. The box is small enough to leave room for extra snacks/treats. The thermos and the rubber lining come out of the box and the lid, rim cover, and thermos itself are fairly easy to clean.

I got this for my kindergartener, and the size is perfect for him. I realize it’s marketed for ages 9+, but honestly, I find this one more suitable for us than the standard square OmieBox with all the extra compartments and smaller jar. I originally planned on getting the standard OmieBox, but quickly realized he really doesn’t need all the extra separate compartments. He’d much rather have more hot food in the larger jar. On days when I’m not packing a hot lunch, I use our silicone separators to create additional compartments in the large space, which works out perfectly. To be honest, the main reason I love the OmieBox is the square securing insert piece that keeps the jar anchored in place. Otherwise, my son would try to open the lunchbox with both hands, and I can already picture the entire contents spilling onto his lap. I couldn’t find any other lunch boxes (dupes and all) with anything similar. A minor complaint would be the silicone name tag holder. This falls off quite easily but it was fixed by replacing it with a small metal carabiner. Overall, this setup works really well for him and gives us the flexibility we need for different types of lunches.

The OmieBox UP Insulated Bento Box is one of the best lunch solutions for kids I’ve come across. It’s designed thoughtfully with separate compartments, making it easy to pack a variety of foods—snacks, fruits, sandwiches, or even warm meals—all in one box. The built-in insulation works well, keeping hot foods warm and cold items fresh until lunchtime, which is a huge plus compared to standard lunch boxes. The materials feel sturdy and high-quality, able to withstand the daily wear and tear of being tossed into a backpack. It’s also easy for kids to open and close on their own, which is important for independence at school. Cleanup is straightforward, and the colorful, kid-friendly design makes it a hit with children. For parents looking for a reliable, versatile, and kid-approved lunchbox, the OmieBox UP is an excellent choice. Highly recommended.

This lunchbox is causing marital conflict in my household. My wife raves about it based partly on the reviews, but after using it for a few weeks for our kids' school lunches, I have to say, what are you people thinking? First of all, the compartments are so small, that for a lunchbox that prides itself on flexibility, it's anything but flexible. Try fitting a normal sized yogurt drink in here - not gonna happen. And the ice pack is so small, it barely does anything. The first few days I started using this, I started taking different dividers out...by the second week, I had taken the entire divided structure out and just put the food in the box itself (where the ice pack is stored). Second, cleaning this is a nightmare compared to a normal insulated box with a few partitions or just an open space. The rubber seal that goes over the top edges comes off easily, and it takes 10-15 seconds or more to push it back on to make sure it's sealed. And there are so many compartments to clean... and then reassembling everything takes time as well. Nice idea, but not practical at all for children's lunches, both from a time perspective, and also flexibility perspective. 1 star just to offset some of the 5 stars (which can't be serious). My wife takes it personally that I hate this lunchbox, but I'm not wavering - don't buy.

We have the smaller Omni lunchboxes and I wanted a bigger option for my growing son. These lunch boxes are awesome because they have the thermos option to keep lunches warm and dividers for different items. There’s only enough room for 2 sides, which is actually easier for my 8 year old—too many options means longer lunch and less recess. He sometimes has a hard time closing the lunchbox so I’ll get it back and whatever he didn’t eat will have spilt all over but other than that I love the durability and when it is closed correctly it is super leak proof. Not to mention it’s super cute and modern looking, love the colors and solid feel. I highly recommend this lunchbox for big kids. I also love that it has a little cold pack that goes inside the lining of the box to keep sides like fruit and salad cold. Everything comes apart easily making cleaning a breeze, love that!

It’s okay. The thermos fits a pack of ramen which is my daughter’s lunch of choice. It does keep the food warm for a good amount of time. I pack my child’s lunch at 7 am and she eats at 12:50 pm and she hasn’t had any complaints about it not being warm. She says that the lid for the thermos is fairly easy to open, which I guess is nice. To me the plastic feels super cheap though. It looks okay, it’s definitely nothing special. The little divider for the cooled section does well at separating the food and not sliding around. The ice pack that comes with it is honestly too small to be effective for long. The box is absolutely NOT leakproof like it claims. The gasket only goes in one way so it’s certainly not operator error. That part is very frustrating because it definitely limits what can be placed in the box. Overall, the only great thing about this box is the thermos. That part works beautifully.

I’ve been using the OmieBox UP in Cherry Pink for my 5-year-old for a few months, and it’s made school lunches so much easier. The standout feature is the vacuum-insulated stainless steel food jar in the main compartment. I pack hot pasta or soup in the morning, and it’s still warm at lunchtime. The bottom cooler ice pack keeps yogurt and fruit cold—no need for extra ice packs. The two compartments are the perfect size for a main dish and sides, and the entire box is completely leak-proof. I’ve tossed it in a backpack sideways with no spills. Pros: Keeps hot foods hot and cold foods cold for hours. Easy for little hands to open the latch and spoon. Dishwasher-safe parts (top rack) make cleanup simple. The silicone seal is sturdy and hasn’t worn out. Cons: The overall size is a bit bulky for small bags. The thermal jar capacity (around 8 oz) is fine for a young child but might be small for older kids. Also, the price is higher than basic bento boxes, but the insulation justifies it. I absolutely recommend this to parents who want one container that handles both hot and cold items without leaks. It’s durable, cute, and actually works as advertised. My daughter loves the color, and I love not packing separate thermoses. Worth every penny if you need a reliable hot/cold lunch solution.

My daughter had the original version and it was super bulky. I love this smaller version. It’s on the more expensive side but the quality is amazing! Definitely worth it and will last a long time. Absolutely love that it has a cooler pack for the side compartment. Perfect for fruits & veggies or anything you want to keep cool. I pack lunch for my daughter everyday. I love that this thermos has a wider opening than the old one. It’s easier to clean and fits more food. It’s easy to clean. My ONLY negative is the rubber strap that comes off easily. Other than that I love this product!

It’s a great product, well made and designed. However the rubber seal keeps coming so need to be careful not to lose it. Bought the wrong size for the age category I needed which is primary school age but ended up with the secondary school age box. Too expensive to not use so I’m making it work for now.

Love our OmieBox UP. We use it everyday for lunches and the thermos keeps food pretty warm. We have it for our 6 year old and 4 year old and they are happy with the quantity of food the thermos holds. Really glad there’s a section for cold with the ice pack underneath too. The lid of one of the thermos’ broke because our 6 year old yanked it off (!) and we reached out to them to buy a new lid but they sent us a form to complete as we were apparently still under the warranty period. We got sent a brand new thermos AND lid in under 48 hours. Their customer service is fab. I’d definitely buy again and I am a self declared Omie brand ambassador.

Name tag falls off very easily and the thing that secures closure got broken a couple of weeks after using. Totally not worth it

Love this, it's perfect. The food stays hot for a long time and I can add some salad or extras in the compartment. My daughter loves it as it's compact!

i’m in love with this!!! perfect and does the job, just the perfect portion sizes for me
