Sometimes it’s just fun to look at dinosaur bones on your pen! This Retro 51 Smithsonian Collection: “Dinosaur Fossil” Tornado Rollerball Pen is officially licensed by the Smithsonian. Inside the commemorative tube, you’ll discover a metal pen where you can actually feel the dinosaur bones. It’s been plated in stonewashed copper to give it an unearthed look and then top printed in ivory to highlight the several dinosaur bones that wrap around the barrel. This distinctive pen is sure to make you roar and makes a great gift idea!
