The **Boston 2018 Returning Challengers (Holo-Foil)** sticker is a flashy relic from CS:GO’s ELEAGUE Major, where teams like FaZe Clan and Cloud9 battled for glory. Its holo effect gleams with pixelated pride, shimmering like a disco ball at a 2010s LAN party. While it lacks the prestige of the Champions sticker, it’s perfect for flexing on budget skins or trolling teammates with its “I was there” energy. The animation pops best in dark corners of Vertigo, making it a favorite for players who prioritize style over subtlety. Just don’t ask why anyone pays $10,000 for virtual glitter—it’s CS:GO logic, baby.
