I have a black Jinhao Century with gold trim on the way from China, as well as a Pilot Justus in medium fine headed my way from Japan. I have a pretty large collection of Japanese pens and never heard of the Justus until last week. It has a feature that allows the user to alter the flexibility of the nib by turning a ring around the base section of the pen which raises and lowers a shiv that sits atop the nib. I gotta check that out - think the fountain pen equivalent of a Fatboy! BTW, I joined the 2024 McGuyver GRUME no buy group for shaving stuff, so I will need to satisfy my buying instincts on fountain pens this year!!!
