The name of this design edition refers to the pen's special lacquer finish. The color progression is sprayed by hand and subsequently sealed with a clear protective coat. This process gives these writing instruments their unique look, as no two pens are alike: each Drehgriffel is unique! The Drehgriffel of the Gradient Edition is a ballpoint pen (Nr. 1) crafted from precision-milled aluminum and brass. It features a spring-loaded twist mechanism for your writing pleasure. The replaceable large-capacity refill has a medium line width. With its hexagonal silhouette, tapered tip and special lacquer finish, the Drehgriffel of the Gradient Edition is a striking statement.
