From Colorverse's Season 3 Multiverse, these glass bottles of Photon (65ml) and Gluon Glistening (15ml) are a beautiful pair. This ink is dye-based fountain pen ink. The glistening ink contains glistening pigment.
Colorverse inks are made in South Korea and are complete with thoughtful design, adorable accoutrements, and very cool packaging.
