This ECOlunchbox Three-in-One is a three-piece nesting lunch box set. This nesting lunchbox makes it also easy to pack a variety of foods and keep them all separate - and safe from squishing! Our Three-in-One is perfect packing a healthy entree and two side dishes. 

The Three-in-One is modular. You can pull out the snack container and use it separately, freeing up more space in the upstairs for more food. For more Three-in-One menu ideas, see here.

Our best-selling bento, the Three in One is a 100% high-quality, food-grade stainless steel container. Because it does not contain plastic, the lunchbox is free of all estrogen-mimicking chemicals, such as bisphenol-A (BPA), phthalates, and bisphenol-S (BPS). But it's not leak-proof since no plastic gaskets are used.

Circular Design  Dishwasher Safe  Reusable

Quality and efficient

My daughter loves her Eco Lunchbox. Easy to open but also stays firmly closed. Perfect size for lunch plus snacks for a long day at summer day camp. Easy to keep clean. Quality materials. Glad we made this purchase.

So well made!

We love these lunchboxes! We have 2 already and got 2 more so each kid has their own. I love that food only touches stainless steel, they are easy to use, and virtually indestructible! The only issue I wanted to note was that they have changed them slightly from the last ones that I bought and they are not interchangeable, which is frustrating.

Great lunchbox! A bit smaller than anticipated

Great! It cleans easily and it is wonderful to have a lunchbox that is not made out of plastic or glass. The compartments are wonderful and fun to use too.

Excellent sturdy lunchboxes for a good price

I purchased these lunchboxes as a Christmas gift for my brother, and we're both very pleased with them! His old lunchbox containers were cheap plastic which cracked easily; these sturdy, stainless steel boxes are the perfect fit for his hardworking lifestyle. Although they look small, the containers hold a surprising amount of food while also keeping it safe. Additionally, they're a breeze to clean and store. Thanks so much!

very pleased

seemed small at first, but after I packed them, they were fine. I send them in insulated lunchboxes to be able to add whole fruit, etc. Wouldn't want them any larger after all
