Description Waterman Serenity Blue fountain pen ink is a bright, vibrant shade of blue with great flow, and it behaves well in both vintage and modern pens. Rinsing this ink out of your pen is also very easy. The 50ml glass bottle has a clever design. The cap is ribbed for easy opening and closing, and the faceted sides of the bottle allow it to be tipped on its side for easy filling of your fountain pen, even when the ink runs low. Waterman fountain pen ink is made in France. Waterman Serenity Blue fountain pen ink was formerly called Waterman Florida Blue. Having trouble deciding between colors?
