Inspired by the Japan Blue project, Refill Memo Pad Blue 2mm Grid Quadrant Graph is made with high-quality color paper in blue. The refills are bound together on one side through a gluing technique called “tennori”. This allows you to use each Refill Memo Pad on its own like a notebook and detach it to store in your leather binder when you are looking for more portability. The layout is based on PLOTTER’s iconic 2mm Grid, with easy-to-read solid gray guidelines in a 4-division quadrant layout that lends itself to a variety of creative uses. The “quadrant graph” format can be used to map out ideas in separate sections, take notes, or mark to-do lists for different purposes. You can also utilize the 4-box layout as a weekly planner across two pages (8 boxes for 7 days of a week). The paper is strong and tear-resistant. You can enjoy a variety of writing tools on this paper without bleed-through. Please note, this is a notebook refill that is sold separately from the PLOTTER leather binder.
