If you are up to date and responsibly binge watching all the nessecary netflix specials, you have probably watched Strager Thing season 3. Hopper gets a new look and lets everyone know how he feels. If you back Hopper and his apparel choices, check out this pin. 
 
This pin is 1.5" x 1.4" and 2mm thick with double pin backs to make sure it doesn't move once it's placed.
