I joined because this pen is incredible looking. Reading the description, what kind of ink cartridge would this take (or only liquid ink?)? Details are rather sparse.
imaherFrom the "description" section: "This ‘EXT’ model pen offers an extended design that is capable of holding either two international standard ink cartridges or a converter, all of which are included."
So international standard carts.
imaherIt should take any standard international short or a standard international converter since it's an EXT :) A lot of companies do standard international, like Diamine and J Herbin
ApollymiIf it will hold two short cartridges within the barrel, it *should* also be able to fit the longer standard international cartridges favoured by some companies - notably Waterman and Pelikan. If it comes with a converter, though, you can use any bottled ink that's designed for use in fountain pens.
So international standard carts.
