My favourite notebook, I own a few. The cover is amazingly soft and feels great to carry around. Elastic strap works perfectly for holding the book closed.
The paper has this silky feel that can't be beaten by any other paper, and if you use fountain pens, or any very inky pen, this paper will treat it well and the ink will not bleed at all. You could pour a bottle of ink on this and get crisp clean lines.
