Discover the masterful intersection of iconic vintage design and modern resin artistry with the Conklin Duragraph Primary Manipulation 3.5 Fountain Pen.

With a production run strictly limited to only 198 individually numbered pieces worldwide, this instrument is a true collector’s prize, offering an aesthetic that is as bold as it is rare.
The hallmark of this pen is its breathtaking resin body. Created through a complex, multi-pour "primary manipulation" process, the material features an explosion of vibrant, swirling pigments—a technique that allows each barrel to display a completely unique pattern of light, color, and depth. No two pens are exactly alike, ensuring that your instrument is a one-of-a-kind functional art piece. The luminous, organic swirls are elegantly framed by polished chrome trim, providing a sharp, bright contrast that elevates the vivid resin to a level of refined, modern luxury.
Beyond its artistic exterior, the Duragraph silhouette is designed for the expressive writer. It is fitted with a premium stainless steel nib, available in a wide array of sizes to suit any handwriting style, including the highly popular Omniflex nib for dynamic line variation. Whether you are penning personal journals or executive correspondence, the Duragraph delivers a consistently smooth, reliable flow. Housed in a luxury presentation box, this limited edition fountain pen is not just a writing tool—it is a vibrant statement piece for the discerning collector.
