Sprinkle Details

Magic In A Bottle

Twinkle Sprinkle is built with a versatile, well-behaved twinkling pigment that, despite its initial bluish tint, metamorphoses into a neutral sparkle or subtly takes on the hue of the colorant medium upon integration, seamlessly enhancing your chosen ink.

Mix It Up

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

Anticipate headspace in each bottle from pigment integration during preparation.

Pen Maintenance

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.
