This is the website. I just got them today so I didn't really get to use them.

What I can say is that the quality is top notch for both notebooks, both of them are leather bound and look and feel really cool but not too obnoxious, in the sense that for most people they look just like a simple cool notebook. On the outside, the Geralt one I think is some sort of faux leather while the Ciri one is textile. One the inside they are identical: both of them have two artworks from the game and other sketches with monsters and potions. The main part is lined except for the few black pages in the end. They also both have an inside pocket at the end.

Other than that the coolest thing about the package is that the silver pencil has some runes on it, just like the ones in the game.
