Cleaned up and refilled five of my most favourite pens because procrastination. (Three old V SignPens and a couple of Hero 339s.) I love how the SignPens age. The more one wears the nib down, the better it gets. I think I’ve had one in black since Ahmedabad (somewhere between 2007 and 12) and the tip is a flat-ish stub that takes a little getting used to before it gives one a thick-thin stroke. In spite of being metal (or because of it being metal) the 339s age disastrously and flat-nib-temperamental-calligraphically.
