Colorverse inks are made in Korea from plant-based pigments, resulting in amazingly vivid colours that are pH neutral and quick-drying. Their numerous collections are all inspired by the natural world, both down here on Earth and up there in space. The packaging is second to none, with close attention to illustrative detail, and beautifully-shaped glass bottles.

This is a stand-alone set, outside of the usual Colorverse collections and is named for Johannes Kepler, the 17th century German astronomer. It contains 3 mini 5ml bottles of ink: Somnium (green), Planetary Motion (blue) and Conjecture (magenta) featuring the uniquely-shaped Colorverse design: a rounded bottle with a teardrop-shaped base. A rubber seal incorporated into the lid keeps the ink safe. Each bottle is supplied with a pipette.
