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.

The best!
I must say that the Omiebox up is the best!! It keeps your hot foods hot and your cold food cold for hours. It’s definitely worth the price.

An Absolute Must Have!!
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!

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.

Rusting
I am so glad I waited to do the review on this lunchbox. I finally caved in to all the influencers & bought two. One from here in Feb and one from the TikTok shop in march. To clarify both of my children pack their lunch every single day so I have been using a “cheaper” lunch box prior to this. While it’s heavy, and the hard shell outside feels flimsy. It is compact and it has good amount of storage for my 10-year-old lunch. However, I just noticed that both of the Thermos have rust spots already. And you can see the picture I’m including comparing Omie to the cheaper version I had since last year. Same cleaning. same storage. same handling. While my previews review was gonna be like a three star that definitely takes it to one star because I can’t do zero. Parents, please double check the thermos.

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!

A very solid choice!
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.

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.

Too expensive but works
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.

Perfect lunchbox, fabulous customer service
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.

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