I use this binder to hold music charts for a music group I am in each chart is in a viable sheet so after a couple hundred charts it gets heavy. This binder is up to the task. When traveling about it gets battered around. This piece is up to the task!
I've purchased this brand before and it has held up for the last 6 years. I decided to use the binder again because of my previous experience. If you haven't tried this binder I recommend that you do so you will not regret it.
