Description Diamine Shimmertastic Neon Lime fountain pen ink is a bright yellow-leaning shade of green with silver shimmer particles, 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. 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 ink is considered to be well behaved and smooth flowing, and have been made in the UK for over 150 years. Having trouble deciding between colors?
