Van Dieman's Professional Natura Dualis - Sea Spray Dual Tone Fountain Pen Ink captures the delicate mist at the ocean’s edge with a soft seafoam green base accented by blooming lavender-pink hues and cool marine blue edges. This ink reveals luminous halos and gentle internal textures, especially on Tomoe River and Clairefontaine papers, where subtle color shifts create a serene, atmospheric effect. Sea Spray offers a refined, legible flow that evokes the quiet beauty of sea and sky meeting, perfect for those seeking an expressive yet understated ink.
