SAVE on Biophoton Twinkle in the Twinkle Pair.

Biophoton Twinkle is a deep emerald green fountain pen ink infused with a shimmering silver pigment for a radiant, high-energy finish that captures the brilliance of bio-illumination.

This ink is a shimmering spectacle jam-packed with dyes and pigment. A broad nib point grade or larger is recommended to carry the thick viscosity. This supersaturated hue offers approximately 112 standard converter refills from its generous 90mL minimum volume assuming an 0.8mL draw. A small amount of headspace is intentionally left above the liquid in the jar to help with agitation and pigment dispersion.

Our swatch was produced on 68gsm Tomoe River paper, which emphasizes the secondary colors specifically. It's challenging to display the color array of sheening inks on-screen.

***Visible coloring will vary drastically by paper type and saturation.***

Twinkle inks require additional pen maintenance and cleaning compared to their traditional ink peers. Please don't use Twinkle inks in vintage pens or pens that cannot be completely disassembled for thorough cleaning.

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.
