Our best-selling bento, the Three in One is a 100% high-quality, 201 food-grade stainless steel container.

Still using after 7 years

I bought this for my daughter about 7 years ago and it is still just as good as the day we bought it, even after pretty much daily use during the school year! Way more sturdy than the plastic versions, and there aren't any plastic chemicals seeping into her food! The separate snack container is perfect for schools were there is a separate snack time. This is the last lunch container you will ever have to buy! (Note, it is more of a child's size, for a teen or adult I would go with the size large)

Vitamin Approved!

We needed a study container that wasn't plastic to put my daughters gummy vitamins and to store it while we travel. We absolutely love it, and super easy to dry after washing it! We love it and the quality is amazing! Go get yourself one of these!

Kid Approved!

Mama is impressed with how comfortably each layer fits together – sealing non-liquid items much better than I anticipated, and gliding smoothly so the kids can easily open it at lunchtime AND close it before it goes back in their backpacks. What a concept! I have 2 elementary age kids who were stoked to use their new lunchboxes, and they now have friends wanting some of their own. There’s no cringe-worthy metal-on-metal sounds, which I thought it might have since the Classic 3-In-One sets don’t have silicone gaskets. Mom’s happy, kids are happy, and backpacks are clean. What more can we ask for?

Three in one

I knew it was going to be small but I wasn’t prepared for how small. I stuffed a small sandwich for a kid, it fit but barely. Losing a star for the hilariously compact lunch tin.
