The "No Joking" case is for serious players who don't like jokes and are ready to invest big money in the game. In this case, you won't find any funny characters, amusing emotions, or amusing sounds. Instead, there are the rarest and most expensive items that can become a real find for collectors and enthusiasts of exclusive skins. Rumors say that there is one item in this case worth over $100,000. This is, of course, no joke! If you want to be a serious player who has the best equipment and gear, then this case is for you. But remember, there's no room for jokes here, only a serious approach to the game and investments.
