Sailor Ink Studio 370 Fountain Pen Ink 20 ml
Sailor Ink Studio 370 Fountain Pen Ink 20 ml is one of the most elegant and natural green shades in the entire Sailor Ink Studio collection. Its colour evokes Japanese vegetation at the end of summer and the beginning of autumn, combining olive green, mossy tones and subtle yellow undertones that create a calm and sophisticated personality. Like many Ink Studio inks, its appearance changes depending on the paper, nib and amount of ink applied to the page.
The Story Behind Sailor Ink Studio
Since 2005, Sailor has organised Ink Studio events in Japan, where the company's master colour mixer, Osamu Ishimaru, creates custom colours for participants using a genuine ink-mixing bar. Over the years, more than 20,000 different colours were developed, drawing on both accumulated expertise and feedback from thousands of users.
In 2018, Sailor launched an ambitious project: selecting one hundred representative colours from the more than 20,000 shades created through these events. The result was the Ink Studio collection, a series in which traditional colour names disappeared and every ink became identified solely by a number. Part of the experience lies precisely in avoiding preconceived ideas and discovering each colour for yourself.
Each number represents a unique formula developed by Sailor. Ink Studio 370 occupies a special place among the green shades thanks to its balance of natural character, readability and chromatic complexity.
An Olive Green Inspired by Nature
Ink Studio 370 displays an attractive soft olive green with mossy undertones and delicate yellow highlights. It is a colour that conveys calm and harmony, avoiding both excessively bright greens and overly dark shades.
Depending on the paper used, it may evoke dried leaves, damp moss, young bamboo shoots or natural Japanese landscapes. This tonal richness adds visual depth and makes writing particularly enjoyable.
Its balanced character makes it equally suitable for everyday writing, journaling, correspondence, drawing, botanical illustration and creative projects seeking a natural and refined aesthetic.
The Shading Characteristics of Ink Studio
Like many inks in the Ink Studio collection, 370 offers attractive and well-defined shading. Areas with heavier ink concentration reveal deeper, earthier greens, while lighter areas display brighter and slightly more yellow tones.
This behaviour becomes especially noticeable when used with medium, broad or music nibs, adding depth and personality to every page.
Writing Experience
Sailor Ink Studio 370 delivers the excellent performance for which Sailor inks are renowned. Its flow is smooth, consistent and pleasant, allowing users to enjoy long writing sessions comfortably.
This is a non-waterproof dye-based fountain pen ink designed to maximise colour expression and writing pleasure. It offers good lubrication, relatively quick drying times and excellent performance on quality fountain pen friendly papers.

To fully appreciate everything Ink Studio 370 has to offer, we recommend using high-quality Japanese papers such as those available in our Japanese writing paper section.

The Sailor Philosophy
Founded in Hiroshima in 1911, Sailor is one of Japan's leading names in the world of writing. Its continuous pursuit of new colours and unique writing experiences has resulted in some of the most innovative ink collections available today.
The Ink Studio series perhaps represents this philosophy better than any other collection, celebrating experimentation, creativity and the endless exploration of colour.
"Sometimes an ink does not have a colour. It has one hundred possibilities."
