Blackwing has some really nice looking notebooks in hardbound and flexible covers. They come in medium and large sizes with either plain, ruled or square pages. The paper is acid free and 100 gsm. They can be combined with a rather nice looking leather folio ($89). They are found on pencils.com (like most of us, no affiliation). I'm really curious if anyone has tried these notebooks and if they are fountain pen friendly? http://www.pencils.com/journals-sketchbooks/blackwing-notebooks/blackwing-luxury-notebook-folio-medium http://www.pencils.com/journals-sketchbooks/blackwing-notebooks/blackwing-luxury-notebook-inner-refill-medium http://www.pencils.com/journals-sketchbooks/luxury-journals/palomino-luxury-notebook-hardcover-medium
