Inside the commemorative Dino Fossil tube you will discover a metal pen where you can actually feel the bones. It's been plated in stonewashed copper to give it an unearthed look and finally top printed in ivory to highlight the several dinosaurs that wrap around the barrel. The top ring has been engraved with the Smithsonian name, plus it's numbered and then imprinted with the Smithsonian logo on the top disc. This pen is sure to make you roar!
