Bring more creativity to your creative pursuits with the Torpedo GB Roller Ball Pen. Designed by Croatian brand Torpedo GB, the roller ball pen pays homage to the first self-propelled torpedo, completed in 1866. Imaginative and elegant, the design recreates the shape of a torpedo and even features a small propeller, topped with a white, red, or blue Swarovski stone. Smooth and rounded, this roller ball pen is a joy to use, whether you want to sketch or write down a concept. The refill is easy to change when needed and the roller ball pen works with standard cartridges. Except for the hull, all of the components in this roller ball pen are skillfully crafted by hand and assembled with utmost precision. A wooden box made of solid walnut, a white leather pouch with hand-sewn detailing, and a documentary about the world’s first torpedo are also included.
