LAMY Logo Fine Nib ran out of Noodler's Purple Mountain Majesties today.
Finally, the cartridge ran dry.Pilot Metropolitan, Medium nib.
Converter is probably running dry. Who can tell? It's opaque black rubber.
Had Diamine Green Black in it.
I shall replace it with the cartridge of black ink that originally came with the pen.
In the future I can refill that with a syringe.
