The Jansen / De Atramentis scented inks count among collectors as unproblematic for fountain pens, since they flow cleanly and leave no deposits; tested were among others Waterman Charleston without anomalies. Recommended is to first try a new ink in a less valuable pen and, after first drawing up, return the contents to the bottle to observe the residue behaviour. In the bottle the ink scents clearly of the model perfume; on the pen itself less strongly. On good paper and in closed envelope the scent remains preserved for several days; on simple copy paper it dissipates rapidly. To consider is that scented inks partly continue to scent in the cap, and residues can be perceptible longer even after ink change.
