I bought this for my third grader for school as it was the best I could find short of metal. Ask me again in May and I will tell you how it stood up to a year in a backpack.
My son needed a 2" binder for school and this one seems very durable compared to the others available. A little bit more expensive-- but I'm hoping it will hold-up through the school year!
We have bought Staples Better binders for at least 7 years and will keep doing it. Their quality is so good they last the whole school year and more. They also have a nice presentation and fun colors. Love Staples
