Size:  9 1/2” wide x 10 1/2” tall x 4” deep.This is a mini backpack that paid special attention to its size.  Small enough for children, but it can also be customizable to be made for adults.With a vertical zippered pocket on the outside as well as a divided slit pocket on the front interior and a zippered pocket on the back interior this backpack has a place for everything and everything in its place!My tester is made out of repurposed denim and waterproof canvas. Together,it makes a very stiff and sturdy backpack that can withstand all kinds of kids throwing it around.Having said all that, this mini backpack is easily adaptable to be made for an adult.  The size of the backpack would stay the same. What could be changed are pockets and adding adjustable length to the straps.Please message me if you are interested in a special order.  Ideally, this bag would work best with leather and vynil for the exterior and waterproof canvas for the interior.
