The Hobonichi Pencil Board in the A5 size is a chic navy blue with pink grid lines and is designed to fit your A5 Cousin Hobonichi planner. You place it underneath the page you are writing on for added stability and reinforcement. The pencil board is recommended for users who have filled their inner cover pockets with thick items or users who write with a lot of pressure and leave indentations on the opposite pages. The board has a graph pattern ruled into 5-millimeter squares, with one side further labeled by millimeter to act as a metric ruler, and a Today tab on the corner to mark the current page if you’d like to use it as a bookmark as well.
