Most lunch boxes rely on a single insulated layer, which means everything drifts toward room temperature by lunchtime. OmieBox uses a dedicated stainless steel thermos for the main dish, sealed apart from air-insulated side compartments for fruit, snacks, and vegetables. The result: a genuinely hot main and genuinely cool sides, not a lukewarm compromise.

Pair OmieBox with OmieLife's Leakproof Silicone Dip Containers for extra portioning flexibility, and the OmieBottle Silicone Kids Water Bottle (255ml) for a matching hydration companion.

Does the thermos keep food genuinely hot?

Yes, it's built to keep a warm main dish hot for several hours, so lunch arrives ready to eat, not lukewarm.

What age is this designed for?

 Ages 3 to 7. Older kids can move up to OmieLife's OmieBox UP.

Is it actually leakproof?

Each compartment holds up to one teaspoon of liquid; anything wetter belongs in the thermos.

Can it go in the microwave?

No, do not microwave any part or boil the thermos.
