Diamine inks have been around for a long time, and they know what colours work and what colours don't, and this colour is one of their most popular colours to date. This ink was used on April 2010 by Presidents Obama/Medvedev in the signing of the nuclear arms treaty at Prague Castel. There is the option of two different sized, 30ml or 80ml bottles, and with more than 80 different colours you are truly spoilt for choice. All the inks can be used in a fountain pen that is fitted with a converter, or a dip pen.
