Overview
A kids insulated bento style lunch box with a removable vacuum insulated stainless steel food jar built in alongside separate compartments. Designed to keep one warm food item next to room temperature or cold items in the same leakproof box.
OmieBox is built around a single mechanical idea, a stainless steel vacuum jar sitting inside the bento tray so a hot item like pasta stays warm next to cold fruit or veggies without one affecting the other. The company also calls out that seals and dividers are sold as replacement parts, which is a detail that matters for a lunch box meant for years of daily school use rather than one season.
- Removable 18/8 stainless steel vacuum insulated food jar
- Leakproof bento style compartments for hot and cold foods
- BPA and phthalate free materials
- Replaceable seals and dividers extend the box's usable life
Who it's for
Parents packing daily school lunches who want to send a warm entree alongside cold sides in one box, and who value a lunch box built to be repaired rather than replaced when a seal wears out.
Strengths and trade-offs
Drawn from this product's published specifications.
- Removable vacuum insulated stainless steel jar keeps hot food warm for hours
- Leakproof design keeps hot and cold sections in one box
- Seals and dividers are replaceable rather than requiring a new box
- Comes apart fully for thorough cleaning
- At 1.7 lbs it is heavier than a simple plastic lunch box
- Recommended for ages 3 and up, so not built for younger toddlers
Performance notes
The stainless steel food jar is vacuum insulated, meaning it holds a layer of vacuum between two steel walls that slows heat transfer, which is the mechanism that keeps a warm entree hot for hours while it sits inside the same box as cold or room temperature food. Because the seals and dividers are removable and sold separately, the box can be kept in service for years by replacing just the worn part instead of the whole unit, which is the basis for the built to last claim.
