The paper quality in the LEUCHTTURM1917 A5 notebook is generally pretty good, especially if you're into staying organized. According to the manufacturer's description, it uses 80 g/m² acid-free paper, which is pretty standard for notebooks like this. It's usually quite decent at minimizing issues like ink bleeding and feathering with regular pens.
From what we've found, fountain pen users mostly have a good experience with this notebook, but it can be a bit hit or miss with wetter inks. Some folks have noticed a bit of ghosting and, occasionally, bleed-through, especially if you're using pens that lay down a lot of ink, like markers or some felt-tips. It's something to keep in mind if you tend to use heavier inks—you might see similar things with other notebooks in this weight category too.
Apart from the paper, the LEUCHTTURM1917 notebook does have some neat organizational features. It has numbered pages and a blank table of contents, which really helps if you're into detailed note-taking or bullet journaling. The manufacturer seems pretty proud of these features because they make organizing notes easier.
The notebook is also pretty durable and user-friendly with a hardcover that lays flat, which is a lifesaver when writing on the go. It also includes two bookmarks and an elastic closure band that add to its practicality.
In terms of looks, it comes in a variety of colors, so there's room to express your style while still keeping it classic and stylish. According to what we came across, this blend of looks and practicality is appealing to a lot of people.
If you're picky with writing tools, it might be smart to test out your go-to pen on it first. It's a solid notebook overall—just make sure it fits your specific writing needs.
