good to put into almost all kinds of fountain pen. thing is, with pigmented ink, i have to put in a little maintenance on my fountain pens (cleaning it out once in a while) because if i haven't use the fountain pen with the ink in it, it seems to clog the pen up. but it's an easy fix. either keep using the fountain pen or just run the nib over running water and it helps the ink flow easily again. this kind of ink, compared to the 'normal' (dye based) ink, does not 'run'. i find that when it dries up on the paper, you can use a highlighter pen over it and it doesn't run unlike with dye based ink. my daughter loves it as she uses the ink to outline her drawings and then color those drawings in without ruining the outline/running.

Excellent ink for your fountain or drawing instruments. I've used it in technical pens, fountain pens and dip pens and the results have been everything I expected.
