The Blue Marble was the original mix of colors of the Parker Duofold Centennial Mk 1 (Mark 1), which was launched in 1988. Together with a rollball pen, the fountain pen came with gold-plated trims that included a pair of bands at the nib collar, the barrel end, and the cap lip. How do you know that it’s an actual Mark 1? Check the cap—Mark 1s do not have an emblem on the finial. The cap, however, sports the simple etched arrow design that Parker is known for. 

We have for sale a Parker Duofold Centennial Mk 1 (Blue Marble) with an 18-karat gold nib in M. We’re offering only the pen, no box or papers.
