This thing can hold a ton of stuff. There is an extra crease in the top cover that was unexpected. You can see it in the photo. It is that black stripe just to the right of the black edge at the binder end of the binder.
I have to stop buying these just for the sake of buying. I love them so much I have about 8 empty binders on my shelves hoping I find something to fill them with. I took off 1 star because I wish there were more tabs to label the binders after I've used both sides of the label provided.
