The Mnemosyne N183A spiral notebook, made by Maruman Co. in Japan, is an excellent surface for ink drawings, calligraphy, writing, precise drawing, and drafting. The otherwise blank pages have a subtle, light gray printed area for writing a title and date for your work. The smooth, almost slick texture is similar to Rhodia paper. Each pad is double spiral bound and has a stiff, chipboard backing that gives you a flat surface wherever you are. 70 sheets in A5 size (6.25" x 8.25").
