Description Jacques Herbin 1798 Anniversary Kyanite du Nepal fountain pen ink is a rich, deep blue ink that leans toward turquoise and has silver pigment particles suspended in it and comes as a 3ml sample in a plastic vial with a dip at the bottom to allow you to easily get every drop, labeled with the name of the ink brand and color. Kyanite de Nepal is inspired by the gemstone kyanite, which is considered to be a noble gemstone because of its similarities to sapphire. Jacques Herbin does include a fairly strict warning on the box, letting users know to clean out this highly saturated ink from your pen on a regular basis, but the ink is safe for fountain pens. The silver particles settle out of suspension fairly quickly, and these particles can be seen on the bottom of the vial. The ink, and your pen, should be gently agitated before and occasionally during use. Having trouble deciding between colors?
