I already have seven nice pens. With booklets, inner boxes, outer boxes, warranty cards, etc. All the silliness that goes along with collectibles. 
Thankfully I still had the user manual for my Visconti or I wouldn't have been able to refill it tonight. Waterman Violet is the color I chose - a hangover from the glory days in our publishing company. The top editor (me for a few years) used a purple pen to distinguish my comments from the "red ink" used by all the other proofreaders and managers.
