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.

The Joy in the Ordinary series celebrates everyday life. The colours are muted, and even the 30ml glass bottle is a little more ordinary, being a useful - but not outlandish - oval shape. A rubber seal incorporated into the lid keeps the ink safe.
