I used Jelly Roll ball point pens for years and was moderately satisfied, but they just didn't last and seemed to quit working if they sat for any length of time. So a short time ago, I began searching for something as heavily pigmented and lightfast as india ink, but with an application method I liked better than the caligraphy pens.
I found india ink pens that contain their own ink and have a type of felt tip which allow for a more metered flow. They are made by Faber Castell and I got mine in a pack of four, each with a different size tip.... XS, S, F, and M. I got them on ****. Go to **** and search for "Faber Castell fineliner".
