Make your writing sparkle with our new TwINKle inks! These inks contain a shimmering particulate that create a beautifully unique writing line.
We regularly receive feedback from satisfied customers saying that our Twinkle Formula ink series are some of the most twinkly, consistently performing sparkling inks on the market. Josh developed an ink vehicle unique to our Twinkle Formula line, designed specifically to operate as carrier for both the water soluble dye colorant base as well as the (much larger) Twinkle pigment. We've carefully chosen our pigment to operate well in high concentrations relative to our vehicle, and consistently display maximum luster on a wide variety of papers.
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.

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.
Wishy-Washy 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.
