Artists, designers, scientists and architects have an intense devotion to this pad. It is perfect for on-the-go use, with its stiff back cover and a staple-bound, scored front cover that folds back conveniently out of the way. Inside, the extra-white, exceptionally smooth paper is micro-perforated, making them easy to tear off.
