PlanetBox Shuttle is our smallest lunchbox, and is designed to hold small meals or snacks on the go. The PlanetBox Shuttle will accommodate various foods that make a healthy light lunch or snack for most kids and some adults. Many people find that they can pack more food than they originally thought. This is because the top of the PlanetBox lunchbox is raised, so you can pack the bottom compartment high with food. The PlanetBox Shuttle fits nearly 3 cups of food when fully packed!
