This is a two chick Dark Blue M605. There's no evidence that this pen has ever been inked - either that, or it's been cleaned so thoroughly that you can't tell. The dark blue is the first color released for the M605 line. Since then, of course, we've come to look forward to the new special editions every year. If you want to look back and complete your collection, this M605 is a must-have! (CM2)
