I've tried all the Gel pens and just can't get an even flow with them. I use Winsor & Newton Inks in Silver and black and a steel nib pen. The inks are available on-line at Pearl.com or at your local Pearl paint store. I'm sure a google search would bring up many other sources. I've had the same small bottle for 4 years. They dry in 3-5 minutes and can be cleaned up with water. The best part is that flex coat will not harm the ink so you do not need the fixatives or color preserver. These inks come in a myriad of colors.

Good Luck.
