Honeycomb Twinkle Sprinkle

Twinkle Sprinkle is built with a versatile, well-behaved twinkling pigment that seamlessly enhances the dye colorants in a traditional Birmingham Pen Co. fountain pen ink.

Anticipate headspace at the top of each bottle from pigment bottling and for simpler user agitation before dosing.

Before each dropper pull, gently agitate the bottle with the cap secured to disperse the Twinkle pigment throughout the vessel evenly. As a concentrated formula, a single pull is potent enough to transform approximately 10mL of ink, offering significant visual impact without meaningfully altering the ink's underlying color properties.

To ensure optimal performance and longevity of your fountain pens, adhere to the same maintenance and cleaning protocols as you would for other shimmering inks when using Twinkle Sprinkle. For best results, we recommend using this additive in modern pens that allow complete disassembly for thorough cleaning.

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.

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.
