Overview
An insulated bento box for older kids with a 12 ounce thermal food jar that keeps hot food warm up to 4 hours, plus a removable ice pack to chill a separate section at the same time. Made from 18/8 stainless steel and recommended for ages 9 and up.
OmieBox UP is a larger, older-kid version of the original OmieBox, with a bigger thermal jar and a removable ice pack rather than built-in cold packs molded into the tray. The rubber seals come out individually, so a worn seal can be replaced instead of retiring the whole box.
- 12 ounce thermal food jar
- Removable ice pack included
- 18/8 stainless steel, BPA-free
- Dishwasher safe with replaceable seals
Who it's for
Parents of kids old enough to manage a multi-part lunch box who want hot and cold food sent together. Not the right size or complexity for younger children or anyone who wants a single-compartment box.
Strengths and trade-offs
Drawn from this product's published specifications.
- 12 ounce thermal jar keeps food warm up to 4 hours
- Removable ice pack for cold items in the same box
- Dishwasher safe with replaceable seals
- Stainless steel, BPA-free construction
- Recommended for ages 9 and up, not younger kids
- More parts to wash than a single-compartment box
Performance notes
The thermal jar holds 12 ounces and is built to keep food warm for up to 4 hours, while a separate removable ice pack chills the rest of the box at the same time, so hot soup and cold fruit can travel together. The stainless steel jar and removable rubber seals are dishwasher safe, and the seals can be bought separately if they wear out rather than replacing the whole box.
