Monotonic

Don't wait for an air-dry after a thorough pen flush to fire up your pen. Instead, run a few milliliters of Monotonic through the complete ink channel and then fill up with your favorite ink right away with minimal operational impact. Without Monotonic, surface tension and viscosity disparity between water and ink create the potential for intermittent hard starts and dry writing until otherwise neutralized in the ink channel. 

Clear away tap water impurities introduced during a pen flush and keep the ink channel crystal clean with Monotonic.  Built with a highly purified water diluent and components otherwise used to manufacture fountain pen ink, our elixir won't leave a trace of harmful residue. 

Gauge the smoothness of a new nib using a quick dip-test without the time-consuming flush and clean-up. A brief immersion into Monotonic will saturate a nib and feeder, providing the lubrication required to test point properties on paper.

Use Monotonic to fill the ink reservoir and lubricate a nib while maintaining a crystal clear line of sight on the point while tuning or polishing, cleanly testing between frictional interludes. 

Monotonic DOES NOT contain ammonia or bleach. Since our gentle formula is built with fountain pen ink components, the elixir should be safe to contact any pen component that is otherwise designed to be in contact with ink.

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.
