This my be bad because I hate saying if but I've really started to look trough the Pen&Ink book (the one with vash the stampede on it) And all the other manga books I own. They all use Pilot "Drafting/Drawing" Ink which is a Pilot fountain pen ink. As I went to the Kinokuniya I picked up the wrong bottle, I got a bottle of Pilot Certified Ink (For Documents) which I might say is one of the most amazing inks I have ever used (its rated top 3 in the Pen&Ink Book) and cost $9.95. I really don't care about prices for Ink as long as its worth it.
Once this bottle is done I'm going to but Pilot Drawing ink and see how it feels.
