Description Diamine Shimmertastic Arabian Nights fountain pen ink is is a rich, dark shade of blue with silver shimmer particles, and comes in a 50ml glass bottle. The shimmer particles do fall out of suspension, so we recommend that you cap the bottle tightly, and use a gentle rocking motion to remix the ink and shimmer together before filling your pen. Diamine fountain pen ink is considered to be well behaved and smooth flowing, and has been made in the UK for over 150 years. Having trouble deciding between colors?
