Pins are a unique and special way to customise your CS:GO Inventory.
Collectable Pins were added as part of the February 26, 2015 update and are available to purchase at Valve-sponsored competitions such as ESL One or DreamHack tournaments or Valve-sponsored promotional events. Attendees of such events can purchase a physical collectible pin package. The package contains a redemption code redeemable for a virtual pin embossed to mimic their real-life counterparts.
To activate go to your top left of steam window, click on games and click on "activate a product on steam".
