This is my second Moonman/Majohn and looks great and well made, my first Moonman was the T1 r/fountainpens · 3 pts · thread
The Moonman T1 was also my first Moonman and I love it, works great, looks nice and very well made. r/fountainpens · 2 pts · thread
Oooo I love my T1! The only reason I don’t use is that much is it dries out pretty quick. Suuuuuuuper smooth writer though. r/fountainpens · 2 pts · thread
