Excellent in all aspects. Its price is certainly high, but if you want a reference paper to write even with a dip pen, it is unbeatable.
Surely at this price, it is not for simple notes, but if you want to write something that you want to last, it is worth it.

Excellent notebook, its paper is ideal for use with a pen. On top of each page, it has a header for title/date, which personally suits me, and the spiral means that the page is always flat.
