I got my first fountain pen around late 2017, curious about the writing experience. It was some kind of Jinhao (not pictured) that isn't often in circulation any more because despite being labeled as a fine nib, it writes way too heavy for me.
Pictured are the pens I typically keep in use:
Pilot e95s (F)
Pilot Metropolitan (F)
Pilot Prera - Slate (F)
Pilot Prera - Demo Green (F)
Pilot Vanishing Point Decimo (F)
TWSBI Diamond 580 ALR (F)
Pelikan Souveran M400 (F)
Faber Castell Ambition (M)
The M400 is the newest addition. The Preras were recently cleaned out and are awaiting new ink.
Not pictured, my current ink collection consists of:
Diplomat Burgundy
Graf von Faber Castell Cobalt Blue
Pilot Iroshizuku Fuyu-Syogun
Pilot Iroshizuku Murasaki-Shikibu
Pilot Iroshizuku Shin-Ryoku
Waterman Intense Black
Waterman Serenity Blue
Somtimes I look at my Pilot steel nibs (Metro and two Preras) and think I should have gotten some other sizes for variety. Then again, I really like writing with fine nibs.
My favorite tends to be whatever I wrote with most recently.
