Austen is our signature leather, chosen for how quickly it develops character. This full-grain, vegetable-tanned leather starts smooth and polished, then begins to change with use. Every mark, every crease, and every day of handling becomes part of the leather, creating a rich patina that reflects how it has been used. These marks are not flaws. They are what give Austen its depth and character over time. If you want a notebook that stays pristine, this is not it. If you want one that becomes uniquely yours, this is the one. Why Choose Austen Shows marks and wear early, not years later Builds a rich patina through daily use Records your habits, not just your handling Deepens in tone and character over time Designed for those who want leather that changes About the Number 10 The Number 10 is built for flexibility. It works as both a folio and a traveler’s notebook, allowing you to switch between bound notebooks and insert systems without changing your setup. This makes it one of the most adaptable formats in the lineup. As the leather ages, the larger surface area creates more visible character, giving the piece a strong presence over time.
