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. Wash Me! All of our items are 100% washable (except for lunch-lined items). Throw them in the washer on the delicate cycle, cold water, and lay flat or hang to dry! It's perfect for kids of any age and even tweens, and the easy-care construction can handle whatever your kids throw at it. Plus, it's machine-washable for hassle-free maintenance.
