Developed by Midori since the 1960s and continuously refined since, MD paper is built specifically to resist bleeding and feathering across nearly any writing instrument — fountain pen, pencil, brush — while staying smooth enough for fast handwriting. The notebook has no traditional cover; instead, the exposed cloth spine tape shows off the binding itself, a deliberate design choice rather than an omission.

Thread-bound construction lets the notebook lie flat at any page, and it comes with a ribbon marker and coordinating label stickers for archiving once filled. Available across A6 to A4 sizes in blank, ruled, or grid formats.
