Retro 51 Smithsonian Dinosaur Fossil Rollerball Ballpoint Pen You don’t have to be a paleontologist or travel back in time to see dinosaur fossils with this officially licensed Smithsonian rollerball pen from Retro 51. Dino Fossil is the next design in the Smithsonian collection, made for the National Museum of Natural History which will unveil a redesigned dinosaur exhibit in 2019. Inside the commemorative tube, discover a metal pen barrel where you can actually feel the dinosaur bones. The Dino Fossil is 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.
