Hobonichi Lined Notebook - A5 This notebook has thin and durable Tomoe River S paper and opens completely flat.The ruled line design was developed by Prof. Haruo Hibino and his team of researchers at BB STONE Design Psychology Unit, Inc., a venture company of Chiba University’s Faculty of Engineering.Hobonichi loves to help kids get out of their study slumps, and help adults concentrate with a notebook that’s comfortable for their eyes. That’s the wish that brought about this ruled line design that focuses on reducing eye strain and based on design psychology.The ruled paper is unique in that the horizontal lines crossing the page are interrupted by short vertical lines that form a subtle grid. However, they perceptually look like straight lines, because of an optical illusion caused by the way our brains work. This notebook comes in two sizes: A6 to match the Original, and A5 to match the Cousin. The A6 size notebook is 8mm thick and contains 240 pages, while the A5 size is 10mm thick and contains 288 pages. This gives you plenty of space to fill the notebooks to your heart’s content. Because the book sizes match the A6 Original and A5 Cousin Hobonichi Techos, you can use these notebooks with a techo cover.
