This handy little book has been manufactured in Japan, unchanged from 1959 until the introduction of several new colors in 2019. Originally designed for surveyors taking notes outdoors, it's been adopted by the general public as an ideal walking-around notebook for writing and sketching with all kinds of pen and pencil. The hard cover allows you to write standing up, despite the very slim size of the notebook. The paper is dirt and water resistant, so feel free to take this sketchbook with you on your next adventure! 40 sheets (80 pp.) per book.
