For over half a century, Sailor Pen has been deeply passionate about crafting nibs with 21K gold, to deliver the most exquisite writing experience. Whereas most conventional gold fountain pen nibs are made of 14K gold (58.5% purity) or 18K gold (75.0% purity), 21K gold boasts a higher purity at 87.5%. With higher purity, gold becomes more supple. At the same time, it becomes more difficult to craft because of its flexibility. We overcame this challenge with an original alloy composition and cutting-edge technology. Today, Sailor Pen is the only manufacturer in the world that produces 21K gold nibs.
The 21K gold nib is engineered to resist ink interruption even under heavy writing pressure. It glides across the paper with a supple, flexible grace, offering a consistently stable ink flow and a superb comfort often described as the “feather’s touch.” Sailor’s nibs have been repeatedly honored with the “Best Writing Experience” award by the American specialty magazine PEN WORLD, earning global acclaim for their peerless performance. Furthermore, with years of cherished use, the nib gradually adapts to the writer’s unique angle and pressure — evolving into a personalized writing instrument that is yours alone.
