This item commemorates the 2019 StarLadder Berlin CS:GO Championship.

 

This 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.

 

This sticker was autographed by professional player Aleksi Virolainen playing for ENCE at Berlin 2019.
