Best lunch box so far
Been through so many lunch boxes and this one is a winner for our style boxed lunches. My daughter likes warm dinner leftovers instead of a sandwich or cold meal, and she doesn’t like too many extra things. So one big thermos container which she can easily open and an extra space for some veggies or fruits works great. According to her it holds temperature very well. It’s a bit heavier than other boxes but I removed the ice pack for minimal release. Seems durable, holds food well and doesn’t spill and it’s easy to use for little kids. Even though it seems expensive, it’s worth it. I wish I didn’t waste money on all other cheap boxes.

Perfect Upgrade Lunchbox!
The OmieBox UP is a total game changer for school lunches. The larger 12 oz thermos keeps food warm for 4 hours (I tested it), while the built-in ice pack keeps cold items fresh, so you can finally pack hot and cold in one box. Everything stays neat and leakproof. I also love the thoughtful details: removable parts for easy cleaning, dishwasher-safe trays, and available replacement seals and thermos parts, which means this box will (hopefully) last for years. The sleeker design is great for older kids, and the colors are fun without looking “too little.” Yes, it’s an investment, but the durability and flexibility make it worth every penny. If you want a lunchbox that actually makes packing easier, this is it.

Perfect Lunch box
Perfect for my 4th grader who likes warm food and salad or fruits on side. Size is perfect and durable. Little heavier than others.

Perfect for leftover loving eaters!
Love this so much. It fits in a standard lunch bag-we use the Bentgo one, which makes it super easy to transport to and from school. My daughter is all about leftovers for lunch. She has no issues opening and closing it by herself including the thermos. Her pastas, soups and casseroles are still warm by the time she eats lunch. I really love that the non thermos side has an ice pack below so you can have the hot and the cold all in one. So convenient and leak proof with the seal. Quick and easy to clean. It’s also a total workhorse when it comes to durability. My daughter has dropped it many times and you can’t tell. Highly recommend!

Practical, Durable, and Perfect for Kids’ Meals
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.

The one thermos that actually works!
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.

Omie goodness! This lunchbox is great!
Good size for a child's lunch! Has a separate compartment for cold or snack items and comes with a freezer pack to keep that area cold. Thermos keeps food hot and is large enough for a substantial meal. There is a gasket that helps seal the inside of the box but it is separate and a little difficult to put in place. Overall, well made and if good quality! Highly recommend!

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
