Waterman Expert Mars Black GT Fountain Pen
I’ll admit I was skeptical about the Hongdian C1 at first, particularly since I rarely use fine nibs.
However, any hesitation vanished the moment I put pen to paper. The writing experience is truly charming and smooth. I’m also impressed by the included converter, which holds a generous amount of ink.
It has quickly become a staple in my daily rotation—so much so that I’ve already purchased four more! I have gifted the white one to one of my friends who also become very happy. The yellow one is hijacked immediately by my daughter!
Kudos to Online Mantra for the excellent service.
