Making it easier to be plastic free

Three-in-One Classic

Why you’ll love it: 

ECOlunchbox’s Three-in-One Classic is a three-piece nesting bento lunch box set. This nifty bento container makes it easy to pack a variety of foods and keep them all separate – and safe from squishing! Their 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.

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. This is an all around best-seller!
