TWSBI Obsidian Fountain pen

Review Title: Lovely Pen - good for left hand overwrites

Average Rating: (5)

Had this pen for a few months now and love it. Very smooth, and though I have the Fine tip, it still flows nicely as a lefthander. No regrets.

TWSBI Obsidian Fountain pen

Author: Fred Traanman

Review Title: Melkweg pen.

Review Add on: 03-04-2026
Average Rating: (4)

De pen afgehaald in de snoepwinkel van Appelboom. Ik heb de pen met een EF nib en ge-inkt met Rohrer&Klingner IronGall Salix. Zelfs met deze nib nog shading waar te nemen.

De pen zelf is erg fraai. De shimmering in de zwarte hars doet een beetje denken aan iets zoals de Melkweg. Geen miskoop.

Review Title: A swirling pint of Guinness!

Review Add on: 26-01-2026
Average Rating: (5)

Every 3 years or so, TWSBI produce something special. Not their ususal demonstrator special editions, but a resin pen. So, following their Aurora, Draco and Kai, 2026 brings the Obsidian. The swirling, moody dark marble resin reminds me of a settling pint of Guinness. The bronze trim adds to the pen's charm, it writes well and always puts a smile on my face!
