 Today we're going to check out the Retro 51 Smithsonian Tornado National Zoo Panda Rollerball Pin. Retro 51s are one of the most collectible brands out there and people love the tornadoes for a few reasons. They write really well. They're come in really fun designs in addition to just being really fun to collect. They're very usable. Their tornado has a twist neural top to extend the rollerball point and you can order a regular Parker style refill for these or you can go ahead and order the Retro 51 refills if you just really love the way the retro is right. These pins are individually numbered on the top ring and you'll notice they have the Smithsonian logo. The National Zoo Panda came out in commemoration of 50 years of panda conservation and that was a really fun one. So this is a good look at the panda and you can see us using the twist neural top here to extend the rollerball. And then here's a look at some of the others in the collection. The Smithsonian is a licensed pin. Retro 51 work with the Smithsonian Museum and they all come with a Smithsonian commemorative tube. And you can see that they have the same top disc there and that's the Smithsonian collection. The other thing people really love about the tornadoes is how well they write. They just run smoothly across your paper. If you're already a big fan of retros, I hope you enjoy this quick look at some of the Smithsonian collection pins. And if you're not a retro collector, you might want to consider adding one to your collection. Follow us for more and visit pinchley.com.
