SAVE on Neutron Star Twinkle in the Twinkle Pair.
Neutron Star fountain pen ink bursts onto paper with a dazzling array of blues and sheening iridescent purple-pink, drenched in our striking Twinkle Formula pigment. Quality fountain pen papers will produce secondary sheening colors most prominently and lower-quality sorbent papers will produce coloring closer to the ink's rich dark blue base hues.
*Fountain pen ink sheen properties are best expressed when the ink is saturated on slightly hydrophobic papers like Tomoe River or Rhodia. Get the best results with a wet line. Visible coloring will vary drastically by paper type and saturation.
Our swatch and writing sample is produced on 68gsm Tomoe River paper, which strongly emphasizes the secondary colors specifically (making our samples look purple on camera.) It's difficult to display the color array of sheening inks on-screen.
Twinkle inks require additional pen maintenance and cleaning compared to their traditional ink peers and perform best in a pen with a medium-sized nib or broader. Please don't use Twinkle inks in vintage pens or pens that cannot be completely disassembled for cleaning. Secure cap and gently agitate pigment to disperse prior to filling.





Technician Log
A Chemistry Of Color
How It's Made
Our fountain pen ink formulas are developed in-house using fine colorant and a meticulously tuned vehicle. Every bottle reflects our commitment to performance, value, and creative exploration.
Formula Guide
We've compartmentalized our fountain pen ink recipes into four principal categories characterized by differentiating elements of the colorant component in the formula. A colorant is a dye or pigment that exhibits color. An ink vehicle is a series of chemicals used to transport colorant from storage reservoir to substrate (paper in our case).
Keystone Formula inks are engineered using water-soluble dyes to produce a broad spectrum of colors with a variety of unique and desirable writing properties. Fitting the bill for a traditional fountain pen ink, this series by far the most popular.
Delicate Formula inks are constructed with dyes selected for both performance and washability. Colors in this series will clean easily from most fabrics and surfaces with soap and water.
Everlasting Formula inks are compounded with pigmented colorants to produce highly water-resistant and archival properties on most papers.
Twinkle Formula inks are formulated using hybrid dye and pigment combinations to create a unique twinkling luster.
