Robert Oster Grey Seas is a weathered blue-grey with faint violet undertones and the changing atmosphere of water beneath an overcast sky. Its broad range of light and dark tones gives handwritten lines a soft, clouded depth.

High shading is the defining quality. The ink moves gracefully between pale blue-grey and deeper slate, making it especially expressive in medium, broad, and stub nibs.
