I bought two of these binders and so far I'm very pleased. I especially like the soft plastic on the sides as I think that will make them last longer than other ones I have used. I also like that there is a place along the spine to put a label. This allows me to stay organized and look professional!
Lots of varying sizes to fit any number of papers. Like the various colors to organize lessons by category. Would definitely (and have) bought this product again. A bit pricey but overall worth it.
