Combining the utility of a highlighter with the precision of a fountain pen, the Pelikan M205 DUO is now available in a limited-edition shiny green. It comes on the heels of the award-winning original, the DUO Yellow, and features the same double-broad stainless steel nib and accompanying bottle of matching ink. Like the rest of Pelikan’s lineup, this pen is fitted with the company’s proprietary differentiated piston filler, which is able to carry more ink and fill faster than other mechanisms. The transparent demonstrator-style body offers a glimpse at the piston filler in action.
