I use this notebook for my college classes. It is compact enough to store inside a three ring binder. The page thickness allows me to write on both sides of the paper. I do not have to worry about sheets ripping out because the binding keeps them securely in the book. I prefer this binding over the spiral notebook because I always "catch" the wire of the spiral on things. I can combine the notebook with post it flags in order to label sections or I can leave the pages unmarked if it is my choice. I also like the fact that it is wide ruled it allows me plenty of space for writing.
