If you have a lot of papers do not buy this product. I am dissapointed in this notebook. I thought it was going to work for my needs but it did not. It looks really durable but the rings are already NOT closing after just putting all my papers in it -- I probably opened the rings not more than 10 times.
I have used one of these binders everyday for over a year and have had excellent value from it. It has performed so well that I recommended one to my boss.
