Robert Oster x Joshua Thorp Olive You Fountain Pen Ink is a natural olive green ink with a slightly earthy tone that sits between green and brown. Created as part of the collaboration between Robert Oster and Joshua Thorp, it reflects the collection’s focus on subtle, thoughtful colors rather than bright or overly saturated shades.
On paper, it shows a muted olive base that can shift depending on the pen and paper. In lighter strokes, it can appear softer and slightly yellow-green, while wetter writing brings out a deeper, more grounded olive tone with hints of brown. The ink has gentle shading, so the color moves between light and dark areas within the same word, giving it a more natural and slightly textured look rather than a flat line.
In everyday use, it flows smoothly and works well for journaling, notes, or writing where you want something different from standard blues and blacks without being too bold. Like most Robert Oster inks, it is not water-resistant, so it can fade if exposed to moisture, but on good paper it performs consistently and keeps its calm, understated character.
