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.
Pros and cons
- 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.
