I love these notepads. They are the best for pencil or pen drawings. I have even painted with markers and watercolors, and the paper can handle it all.
The only downside is the size. I bought it to quickly make small sketches, but it is very inconvenient to paint on such a notepad. I have to put something at the same height under my hand.
Also, because it probably doesn't show in the pictures, the pages are somewhat yellow, not white.
