Whitelines paper is tinted grey so the grid is bright white, sort of like a negative image of typical boring graph paper. It reminds me of an earlier version of non-photo blue grids because when you reproduce pages from the notebook, the lines disappear and all you see is the text or drawing. The paper is also 80 gsm so it's good quality, heavier paper that's much more pleasant to use than normal loose-leaf or typical spiral notebook paper. I bought a huge stack of them in the early 2000s, and still have 5 left. At the time, they were $4.50 each, which seems like a lot compared to the Walmart back-to-school 25 cent special paper, but these notebooks are 48 sheets of A3 paper folded, so there are 96 pages in the notebook. I definitely recommend for students who study science and mathematics, or those who need grids for work or personal use. The only problem with them is that they have become much more expensive and harder to find than it used to be.
