Berlin 2019 Returning Challengers Autograph Capsule
This capsule contains a single High Grade, Foil, or Gold sticker autographed by one of the players from Returning Challengers teams at Berlin 2019.
That sticker can be applied to any weapon you own and can be scraped to look more worn. You can scrape the same sticker multiple times, making it a bit more worn each time, until it is removed from the weapon.
