When I first started out with calligraphy, I fell in love with the Tombow Dual Brush Pen. The resulting style when I wrote with it became something that people came to identify as my unique style (though I contest that my style is constantly evolving). It seemed appropriate to use the Tombow Dual Brush to pen the Tinlun wordmark, and I've since applied new lettering principles that I've learned along the way to tweak and polish the forms.
