I do like filler paper better than notebooks just because it takes too much time to rip notes out of a notebook. I also like that I don't need to carry an extra notebook with me I just put the filler paper in the binders I need. Plus it's not a huge mess of paper shreds with filler paper. However why is paper so expensive? I also like that one container of filler paper can last me a whole year whereas one notebook only lasts about a month.
My High School aged children will only use this paper because it is actually larger than any other binder paper. They can write more on it and therefore use less sheets.
