The Sailor Ocean Slim fountain pen translates into a Japanese writing instrument the real colors of the seas observed from space by the Crayon Project Satellite. The Eleuthera Island and Syvash shades combine an evocative translucent barrel with the precision of a 14-carat gold Sailor nib.

Available in seven nib widths, this refillable fountain pen is suitable for everyday writing, correspondence, and collecting. A portion of the project's sales contributes to marine environmental protection efforts in Japan's Seto Inland Sea.
