Sailor Studio Ink Bottle (737 Purple - 20ML) 13-1210-737

Product Overview

Sailor’s Ink Studio 737 Purple is one of the deeper, more atmospheric entries in the Ink Studio series — a collection of over 100 dye?based fountain pen inks developed with attention to color nuance, flow performance, and pen safety.
This 20?mL glass bottle offers both elegance and practicality. The packaging includes a set of converter labels to help users mark which ink is loaded in each pen (helpful when rotating inks). 

Color, Tone & Visual Character

• Hue & Depth: 737 presents as a “deep, blackened shade of purple” — leaning toward a plummy, wine?maroon base when viewed in moderate light, yet dark enough to evoke mystery and depth. 

• Sheen: One of this ink’s most striking traits is its green sheen. On sheen?friendly paper and in heavier or pooled strokes, the purple base gives way to a glowing green halo, giving it a slightly paranormal, otherworldly appearance. 

• Shading & Variation: The ink demonstrates medium shading — tonal variation becomes visible in wetter strokes or broader nibs, allowing some contrast between lighter and deeper regions. 

• Chromatography / Edge Effects: In watercolor or wet spread tests, 737 bleeds out pinks and greens at the edges. This behavior indicates layered dye composition and contributes to its visual complexity. 

Performance, Behavior & Practicals

• Flow & Wettability: Reviewers report that 737 writes with a wet flow, eager to draw ink onto the page. On quality paper it feels responsive and smooth. 

• Drying Time: Dry time is moderate to slow, especially on very absorbent or coated papers. On Tomoe River 52?gsm, for example, smudging is possible if not allowed to dry well. 

• Bottle / Physical Specs: The bottle is a square glass form (approx. 20.6?mm opening, typical of the Ink Studio line) and holds 20?mL. 

• Pen Safety & Cleaning: As with other Sailor dye inks, 737 is formulated to be fountain-pen safe and relatively easy to flush from pens, though routine cleaning is still recommended. 

• Water Resistance: The ink is not water resistant — exposure to moisture or direct water contact will cause bleeding, feathering, or partial washout. 

• Feathering / Bleeding / Show?through: On fountain-pen-friendly paper, feathering is minimal, but on more absorbent or lower-grade paper, feathering and bleed are more likely, especially with flexible or broad nibs. 

• Behavior on Different Papers: On premium, low-absorbency, or sheen?friendly papers, 737’s green sheen and tonal depth become pronounced. On standard or “everyday” paper, it will appear darker and more muted, with less obvious sheen. 

Use Cases & Appeal

• Ideal for writers who want a dramatic purple with character — deep and moody, but with surprises (sheen, variation) when paper and lighting conditions permit.

• Works especially well in medium to broad nibs, or pens with wetter ink flow, where the shading and sheen can be showcased.

• Suitable for journals, creative writing, artistic accents, or correspondence where you want a fine balance of readability and expressive color.

• Because its sheen and variation are most visible under the right conditions, it pairs best with high-quality paper or dedicated ink journals.

• The included converter labels make managing multiple inks easier and reduce the risk of mixing.
