The Medium Mint Backpack is a larger version of our Small (Toddler) backpack with more room for books and folders. At 11.5x15 inches, kids as young as 3 can handle this bag if they are required to carry a folder from school to home each day, but it will fit kids all the way up to tween size. If the kids are headed back to school add a matching lunch box in either the Gumdrop Lunchbox style or original Lunchbox style. If they are traveling, add a matching duffel bag or Dopp kit! Add a name or monogram (+$10) to complete your item!
