Pilot Iroshizuku Amo-Iro. I'm not a huge fan of Pilot inks; they always come out rather dull looking for my eyes. #Pens #fountainpens

The 3rd is a Monte Rosa with OM nib
@EgbertS pardon my ignorance, but what's an OM nib?
@antonio106 OM nib is Left oblique medium nib. This Mont Blanc has 14ct nib and was my father's fountain pen, built around 1958
@EgbertS it's a very nice collection. It's amazing how many #fountainpen hobbyists are also chess people. :)
