A CS2 sticker capsule works like a small case for stickers. You open it and receive one sticker from that capsule's list, with rarer finishes such as Holo, Foil and Gold appearing less often than the paper version. Tournament capsules bought from the in-game store open without a key, while the older dropped capsules needed a capsule key, as the Counter-Strike wiki's sticker page explains.
The most traded capsules are tied to Majors. For years each Major got capsules for the teams and the players, sold in the game around the event. When the sale ends, the only supply is what players already hold. Valve changed this at the IEM Cologne 2026 Major: it stopped selling capsules and sells stickers directly for tokens at demand-based prices, saying players in some regions could not buy capsules. Older Major capsules still trade as before.
Why do Major sticker capsules go up in price?
Supply stops, but demand does not. People open capsules over time to get stickers for crafts, and every opened capsule leaves the market for good. If the team on the sticker becomes popular later, or a player on it becomes famous, demand rises against a shrinking supply. Valve also discounts leftover stock at times; the Shanghai 2024 capsules went 75 percent off in January 2025, which shows the sale window is Valve's decision, not a fixed rule.
Not every capsule rises. Some events have so many capsules sold that supply stays high for years, and capsules for teams nobody remembers can stay cheap. Buying capsules is a bet on future interest, not a sure thing.
Should you open or hold a sticker capsule?
Opening gives you one random sticker. Holding keeps the capsule sealed and tradable. Before opening, add up the price of every sticker in the capsule weighted by its odds and compare that with the capsule price; the case EV tool works the same way for cases. Many investors hold sealed capsules and only open when the maths favours it.
Capsules are also part of a Major's other items, such as Souvenir packages and viewer drops, so their prices often move together around the event. Watch the whole set rather than one capsule alone.
