OmieBox Bento Lunch Box: A Trusted Favorite for Hot & Cold School Lunches

Why Your Kid's Lunchbox Might Be a Disaster (And How to Fix It)

Let’s be honest: packing lunch for a kid is basically an Olympic sport. You prep a beautiful, Pinterest-worthy meal at 7 a.m., only to find it uneaten (and maybe fused into a single, sticky blob) when they bring it home. Why? Because the strawberries leaked into the crackers. The mac and cheese turned cold and sad. And little Timmy says the broccoli “touched” his sandwich. Gasp!

Frequently Asked Questions

Can I microwave the OmieBox or the thermos inside it?

Short answer: nope! The thermos is made of stainless steel, which doesn’t play nice with microwaves (unless you're trying to start a fireworks show). To warm up food, just heat it separately and place it into the thermos. The box itself is microwave-free, so plan accordingly!

How long does the insulated thermos keep food hot?

With proper preheating (hot water trick, remember?), the thermos in this hot and cold lunch container can keep food warm for up to 4 hours—plenty of time to make it to lunch. It’s not Hogwarts magic, but it’s pretty darn close for a lunchbox.

Is the OmieBox too big for my toddler’s backpack?

It depends on the backpack (and how many dinosaur toys are stuffed in there), but the OmieBox fits most standard preschool and daycare bags. If you’re using a teeny-tiny bag from a toy store, you might want to upgrade to a real “big kid” backpack. Bonus: it gives your little one an excuse to rock a lunchbox-and-backpack combo look.

Can I use the OmieBox for cold lunches only?

Absolutely! The thermos is removable, so you can turn this into a pure kids bento box for cold lunches—think sandwiches, fruit, cheese cubes, and goldfish crackers galore. It’s flexible, which is why parents love it more than their morning coffee. (Okay, maybe not more, but it’s close.)

How do I clean it without losing my mind?

The compartments and outer box are dishwasher-safe on the top rack—hallelujah! The thermos and sealing gasket should be hand-washed for longevity. Pro tip: get your kid to help and call it a “cleaning adventure.” (Results may vary.)
