A good write up over at Writer’s Bloc touches on the wide range of options available to fountain pen users.
A good every day use brand that I have been happy with is made by Private Reserve. Velvet Black and DC Supershow Blue have been my favorites for a good go-to black and blue ink and is typically what I will include with one of our fountain pens. I’ve also had a lot of fun with Copper Burst in some of our demonstrators as people find that they get more creative when a unique color is at their disposal. Private Reserve ink is available in either bottled or cartridge and is relatively inexpensive if you’re just starting out.
