Since 1931, Yamazakura has been producing high quality paper and stationery in Japan. Designed by +Lab, this innovative line creates a new format for memo/sketchbooks that allows you to create and record your thoughts without bounds. Each slim notebook contains 48 blank, perforated, accordion-style sheets, which can be extended and used in a long format or torn off in individual sheets as desired. The sheets are made of virgin pulp paper for smooth writing. The paperboard covers (complete with elastic band closure) contain more than 40% waste paper pulp content, and come in the muted colors typical of Japan.
