Retro 51 Tornado pens are very near and dear to most pen lover hearts, and I love when they come out with space, aviation, or technology designs with their limited editions!

The most recent of these, Under the Radar, is a limited edition Popper run of just 951 pens with an acid etched, matte black aesthetic paying homage to the iconic Lockheed SR-71 Blackbird spy plane, literally one of the COOLEST pieces of aviation history ever made. First introduced over 50 years ago, it still looks as awesome and stealthy as ever.

These pens of course were a huge hit and almost instantly sold out with retailers, but I have a spare that I wanted to do as a fun giveaway here on The Clicky Post!
