Sailor Inktraveler Naoshima Kon 50 ml Fountain Pen Ink
The Sailor Inktraveler Naoshima Kon 50 ml Fountain Pen Ink holds a special place in the history of Inktraveler. It was the first ink ever developed by Sailor in collaboration with a European company, a project born from a shared passion for writing, Japanese culture and the search for the perfect everyday blue. The result is a deep and elegant colour inspired by the evening sky over Japan's Seto Inland Sea surrounding the island of Naoshima.
Naoshima, Art, Sea and Colour
Naoshima is a small Japanese island internationally renowned for its unique combination of nature, architecture and contemporary art. Located in the Seto Inland Sea, its landscapes change constantly with the light, offering endless variations of blue reflected across the sea and horizon. It was precisely this atmosphere that inspired the creation of Naoshima Kon.
At Inktraveler, our goal was to create a rich and dark blue suitable for everyday use without losing character. A colour capable of conveying both depth and serenity while avoiding excessive brightness or saturation. The result is an elegant, balanced and highly readable ink with natural shading that enriches writing without compromising legibility.
A Historic Collaboration with Sailor
Naoshima Kon represents an important milestone for Inktraveler, becoming the first ink developed by Sailor in collaboration with a European company. The project made it possible to transform a personal vision of colour into a formulation crafted by one of Japan's most respected ink manufacturers.
Rather than being conceived as a seasonal edition, Naoshima Kon was designed as a permanent desk companion. A blue ink to reach for whenever elegant, professional and comfortable writing is required during long reading or writing sessions.
Writing Performance and Experience
As expected from Sailor inks, Naoshima Kon delivers a smooth, consistent and perfectly balanced writing experience. Its formulation performs beautifully in a wide variety of both Japanese and Western fountain pens, while its attractive shading adds visual depth to every line.
Its dark blue tone is particularly well suited to journals, correspondence, personal documents, work notes and everyday writing. Medium, broad and music nibs reveal the ink's shading characteristics most effectively, while fine nibs maintain excellent readability.
Recommended Papers
To fully appreciate the nuances of Naoshima Kon, we recommend using high-quality Japanese papers such as the Midori Cotton Pad A5 or the Life Ginkouka Paper Pad. These papers highlight the natural shading and subtle tonal variations that define this ink.

Maravilloso color
Es cálido como los turquesas pero más oscuro, con una seriedad que permite un uso diario y profesional. La calidad (y el olor característico) de las tintas Sailor es de sobra conocida, nada que añadir a ese respecto. Lo destacado aquí es la tonalidad. Me ha encantado. La he probado ya con un stub, que da un precioso sombreado, y con un extrafino que da un trazo muy legible y elegante. Contentísimo con la compra. Repetiré seguro con esta tinta.
