Approx. 12.5 inches h. 11.5 inches l 5 inches w This bag is in almost perfect condition! Only used once, I just prefer a purse to a backpack. The reason it’s in almost perfect condition is because, as you can see in the last photo, there is a small ink stain near the corner. I’m sure it can come out, I just wanted it to be noted! ETA: From storage this bag is a little bent now but can be loved back to life. I can post additional photos of the backpack if needed! Feel free to ask questions, or make an offer! :)
