This ultra-durable lunch box collection adds a sense of style to kids’ meals away from home. Easier to tote than plastic or metal lunch boxes, our reusable lunch boxes boast lovable patterns and are designed to keep food cool and contained. This smart collection is sized to hold our food storage containers and features a water-resistant polyester exterior crafted from recycled plastic bottles, an easy-to-clean molded interior and straps on the back that easily attach to our Mackenzie backpacks. DETAILS THAT MATTER Shell is woven of tough, water resistant 600-denier 100% RPET polyester. The Classic lunch box features a molded interior so it’s easy to clean. Classic lunch box’s YKK zippered mesh pocket inside holds napkin and utensils (not included). Interior lining is made of PEVA, an environmentally friendly, food-safe vinyl that’s made without chlorine or plasticizers.
