Leuchtturm has spent nearly a century perfecting the notebook, and as far as my personal tastes go, this is their best model yet. They've taken all the goodness of a standard Leuchtturm and distilled it into this softcover, smaller size.
The most discernible feature of this notebook is its soft cover. It's lightweight and flexible, but still adds an appropriate amount of structure. The cover material has a nice, subtle texture. It's not as smooth or as glossy as the standard Leuchtturm, but has more of a matte, pebbly feel to it. Where the old standard Leuchtturm exudes old-world elegance and wants you to bring your Mont Blanc to a very important meeting, this snappy wee version screams "grab your TWSBI; we're going camping".
