Pro: best price for the amount of paper. You can get four of these for less than a multi-subject notebook with fewer pages. Con: personally I prefer a spiral notebook where I can stick my pen inside the spiral. This notebook’s spiral is too small unless you’ve got a skinny pen.
I bought a class supply of these and the price was right for less than a dollar a piece. They are not anything fancy but they will work for the project we are doing.
