This is the fully ruled version of the “365 Days Notebook,” which won an award in the design category at the 23rd Japan Stationery Awards. The 7mm lines allow for ample writing space, and are printed in a very thin, light gray color that won’t get in the way of what you’re writing. By connecting the triangular guides at the top and bottom of the page, you can divide the page into two or four parts to create margin lines. The thin paper makes it hard to believe that there are 368 pages in total, and it’s easy to carry around without taking up too much space.
