The original OmieBox, but all grown up! This ingenious UP version is engineered for the big kid appetite (ages 9 through high school) and is the only bento box that lets you pack hot soup and chilled strawberries right next to each other. It’s designed for real, hearty meals—not fussy little snacks—ensuring your child has the fuel and focus they need, whether they’re tackling a huge test or dominating the playground. With a sophisticated, streamlined design, this box works hard and shows off a little personality, too.

Why We Love It: It solves the impossible lunch puzzle: hot and cold, all in one stylish vessel! The built-in, oversized 12 oz (350 ml) vacuum-insulated thermos is perfect for a proper main course (hello, warm pasta and soup!). Plus, the removable cooling pack ensures fruits and snacks stay perfectly crisp on the side. It’s a high-quality, durable investment designed by parents to simplify life—no more juggling a million separate containers!

Product FAQ +

Q: What is the main difference between the OmieBox and the OmieBox UP?
A: The OmieBox UP is designed for bigger appetites (typically age 9+ and adults). It features a stainless steel thermos that is 40% larger than the original, holding 350 ml / 12 oz.

Q: Is the OmieBox UP completely leak-proof?
A: The built-in thermos is fully vacuum-insulated and leak-proof. The side compartments are leak-proof for thick, creamy foods like dips or yogurt, but should never be used for thin liquids like water or soup.

Q: How long can I expect food to stay warm?
A: Food will typically stay warm for up to 4 hours, which is ideal for a standard school lunch period. For best results, always pre-heat the thermos with boiling water for 5–10 minutes before adding food.

Q: Is the entire OmieBox UP dishwasher safe?
A: No, only the inner tray is safe for the top rack of the dishwasher. The thermos, thermos lid, ice pack, and outer box must be hand washed to protect the seals and the insulation.

Q: How do I prevent odours or mould?
A: This is the most crucial step! The silicone gaskets and lid seals must be removed and cleaned after every single use and allowed to air dry completely before you reassemble the box.

Q: Can I microwave or freeze the box?
A: No, never put any part of the OmieBox UP in the microwave, freezer, oven, or on a stovetop. Doing so will damage the seals and void the product warranty.
