This 30ml glass bottle of Herbin Bleu Nuit fountain pen ink is elegantly labeled and the bottle has an integrated pen rest. Bleu Nuit is the darkest color after the Perle Noire color ink. Herbin uses all natural dyes in their fountain pen inks, which is reflected in the very neutral pH of the inks. The inks are created to be non-toxic, and smooth flowing in your fountain pen.
