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.

Pros and cons

Pros
  • 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
Cons
  • 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.

Frequently asked questions

Can the OmieBox keep food both hot and cold at the same time?

Yes, the removable vacuum insulated stainless steel jar holds a warm item like pasta while the surrounding bento compartments hold room temperature or cold food.

What age is the OmieBox recommended for?

The listing recommends it for children age 3 and up.

What happens if the seals wear out over time?

The rubber seals and dividers are removable and sold as replacement parts, so the box does not need to be replaced when they wear.
