Mike, if it is a fountain pen, I would rather see my customers use a better quality ink than is supplied by the kit manufactureres... on my Fountain Pen Care card, I recommend that my customers purchase a higher quality ink (i.e. Private Reserve). In the long run it makes the pen write nicer without clogs and skips.. at least that is what I have found on my pens. It (and other quality inks) can usually be purchased in any good pen shop. Tony usually have some good deals also... if you want to try some other brands you can also try this place.. http://www.apenloversparadise.com/main.shtml. But I would contact Tony first, he probably has more than one brand on hand..
