: These use a leather "sleeve" that holds standard notebook inserts. This is the most sustainable option, as you can keep the beautiful leather exterior for years and simply swap out the paper when it's full.
Consider how you want to interact with the journal every day:
: Slightly more processed than full-grain to remove imperfections. It is thinner and more flexible, making it ideal for sleek, professional journals.
: Look for high-density paper (typically 100gsm or higher) that is "acid-free" to prevent ink from bleeding through or "feathering."
: More modern and functional, often found on refillable "Traveler's" style notebooks.
: Offer a medieval or steampunk aesthetic and a satisfying tactile "click" when closing.
The "best" journal is useless if the paper can't handle your favorite pen.
