Handmade in Pennsylvania

Our Neutron Star fountain pen ink bursts onto paper with a sparkling array of blue and sheening iridescent purples, pinks, and reds with Twinkle pigments. Visible coloring will vary drastically by paper type and saturation, with high-quality fountain pen papers producing secondary colors most prominently and lower-quality papers staying closer to the ink's base blue hues.

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 very 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 disassembled for cleaning.

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 paper.

Twinkle Formula inks are formulated using hybrid dye and pigment combinations to create a unique twinkling luster.
