Japanese, black resin with gold trim - yep another of my Pilot Custom 742 pens. I have five of these pens, three only available for rotation since my decision to only play with my fun ones.
The nib provides the fun for this pen. This FA nib is flexible in the modern sense of the word. It is not the classic wet noodle nibs we see normally attached to a vintage Waterman. This nib produces a fine line but will extend to a double broad width if you apply pressure.
The standard Diamine bottle, enough said.
I love the shade of this Blue Black ink. It shades pretty well especially with this flexible nib.
