Our Mod Bento Lunch Box, this one with a Steel Gray colored lid, is a patent-pending modular system that lets you move and place the removable dividers each time you pack your lunch. There are three included removable dividers that wall off thick liquids and solids, letting you separate sensitive foods and create customized spaces. This simple design makes it easy to customize the Mod Bento Box, even for kids! Best of all, it fits inside most lunch boxes. It can also be taken to work or school by itself inside a backpack, tote, or briefcase.
