What ink system does the Viper Green fountain pen use?
The pen takes standard international ink cartridges and comes supplied with a Viper converter for bottled ink. When you need a replacement, Diplomat bottled ink in 30 ml bottles is available from Yafa. The converter that ships with the pen is a Viper-specific model; a standard Diplomat converter will not fit this pen.
What does the body of the Viper Green look like?
The body is fully covered with an interlocking scale pattern. On the green colorway, that surface treatment runs across the entire body, giving the pen a consistent reptile-scale appearance from end to end.
Where is the Viper Green fountain pen made?
The finished pen is made in Germany at Diplomat's production site in Cunewalde, Saxony. Diplomat has been producing writing instruments in Germany since 1922. Yafa Brands is the exclusive North American distributor for Diplomat.
What comes in the box and what warranty applies?
The pen is presented in a cardboard box with a warranty card and the Viper converter included. The Viper fountain pen carries a five-year manufacturer warranty.
