This ECOlunchbox Three-in-One is a three-piece nesting lunch box set. This nesting lunchbox also makes it easy to pack a variety of foods and keep them all separate - and safe from squishing! Our Three-in-One is perfect for 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.
Our best-selling bento, the Three in One is a 100% high-quality, 201 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.
