These pencil boards are specially fitted for the Hobonichi Techo Planner / Original, Cousin, and Weeks. Keeping it underneath the page you're writing on allows the reinforcement of the thin, comfortable board to provide an enjoyable writing experience. The pencil board is recommended for users who have filled their inner cover pockets with thick items pushing up the paper, or users who write with a lot of pressure and leave marks 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.
The 2017 edition features a dark matcha green on one side against the enjoyable contrast of a light brown on the other side. The size is also set up to protrude slightly from the edge of the planner page so you can easily find it.
