Clean, well done, and hidden which is something I think is really important in this sort of design.
Very nice, so subtle.
the metal-on-metal smooth sliding never gets old for a pen fidgeter. As a pen spinner, it begs for mastery. The unexpected upside: the brass and titanium (I tested my friends brass) work as a stylus on my iPhone, which comes in handy for me as an artist on the subway, or to quickly mark up a screenshot. I love this pen.
The font is very small but still elegant
