Bento box lovers unite! This Three-in-One nesting set from ECOlunchbox makes it easy to pack a plastic free lunch with a variety of foods and keep them all separate–and safe from squishing! The lunch box set is modular, meaning you can pull out the smaller container to use separately, and free up more space in the upstairs, or nest away and have all your compartments stored in in a convienent locking tower. The Three-in-One is crafted from 100% high-quality, food-grade stainless steel. Note: the locking lids in this product are not leak-proof. To store dressing and dips, the Seal Cup Mini (available here) will easily nest in the upstairs of this set.
