Description Jacques Herbin 1670 Bleu Ocean fountain pen ink is a deep, dark shade of blue with gold shimmer particles and comes packaged in a sturdy, square 50ml glass bottle with a wax seal. 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 shimmer particles settle out of suspension fairly quickly, and these particles can be seen on the bottom of the bottle. The ink, and your pen, should be gently agitated before, and occasionally during, use for best results. Having trouble deciding between colors?
