alt Hacker NewsI think this kinda misses the point of what lost modern pen enthusiasts are looking for.
For one thing, limiting yourself to pre-filled cartridges locks you out of 95%+ of the fancy ink out there, which is sold bottled for use with internal reservoirs.
Some fancier inks also comes in cartridges though. Most of Diamine's collection, Kaweco, Montblanc, Graf von Faber Castell and Waterman comes in international standard cartridges too.
Yeah, Waterman is not that "fancy", but being able to carry 8 long cartridges of Serenity/Florida blue with a dependable pen is hard to beat if you are on the go.
