Whatever I say about the bag is not enough. We bought it in the first grade of elementary school. This year, in the third grade, she still has the same bag. It is as durable as it gets. It hasn't suffered the slightest damage. She has never used the straps on the back, she only drags it with the handle. Which handle is of excellent quality. She will buy another one next year just out of boredom. It comfortably carried all her elementary school books. 5 stars are not enough.
