Like midnight freight, Railroad Spike is a dark steel blue with sparks of burgundy* in saturation.
*While it's possible to find sheen in the Railroad Spike when saturated on slightly hydrophobic papers like Tomoe River or Rhodia, this property may require a wet pen and broad nib to achieve in writing.
Part of the Keystone Formula fountain pen ink line, Railroad Spike is built with traditional dye-colorants. Our ink color swatch is produced with a cotton swab on Tomoe River paper.
The 50mL volume will provide approximately 62 standard converter refills assuming a 0.8mL draw. Glass bottles arrive prepared in our beautifully foiled Birmingham Pen Co. gift box.

A Chemistry Of Color
How It's Made
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.
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 most papers.
Twinkle Formula inks are formulated using hybrid dye and pigment combinations to create a unique twinkling luster.
