Private Reserve Ink, 30ml Ink Bottle; Cosmic Cobalt

Private Reserve Cosmic Cobalt is a richly saturated fountain pen ink featuring a deep cobalt blue color with subtle violet undertones. Its blue-violet character creates a bold and expressive appearance on paper, offering an interesting alternative to traditional blue inks. The color has a distinctive depth that makes handwritten pages stand out while maintaining a refined appearance.

One of the ink's appealing characteristics is its natural shading, which produces variations between lighter and deeper blue-violet tones depending on the nib and paper used. In heavier applications, such as large ink swatches or pooled strokes, a subtle copper sheen may also become visible. Its smooth flow and vibrant color make it a versatile choice for everyday writing, journaling, correspondence, and creative projects. 

Part of Private Reserve's colorful fountain pen ink collection, Cosmic Cobalt offers a distinctive combination of rich pigmentation and expressive color. Whether you're adding a new shade to your fountain pen collection or looking for a more vibrant alternative to standard blue ink, this deep cobalt blue brings character and visual interest to your writing.
