A few weeks ago, the CLG CS:GO squad qualified for the ESL One Cologne Major Event to be held August 20th to 23rd. Today, the team stickers for all the Cologne participants became available in the CS:GO In-game store as well as the Steam Market.
In addition to team stickers, you can also grab team autograph capsules, which grants a random player autograph sticker.
To get your hands on the team stickers as well as the player autograph stickers, you can buy from the in-game store the team sticker as well as the player autograph stickers for $0.99. Or if you're feeling lucky, you can try for foil versions of the stickers in foil capsules for $4.99 each. You can also find all variations of the stickers on the Steam Market.
