Itoya's ProFolio Oasis Notebook is a versatile tool for recording everything from details to plans. Between the simple, silver-printed heavy card stock covers you'll find Nakabayashi paper,  smooth and fountain-pen friendly with minimal show-through. Pages are printed in Nakabayashi's unique format, a rectangular dot grid pattern with regularly-spaced horizontal lines, great for creating organized notes and made even more useful with a place at top of each page for recording dates and other information.
