All CS2 Weapon Cases

About CS2 Cases

CS2 weapon cases are containers introduced by Valve Corporation that drop randomly to active players or are purchased on the Steam Community Market. Each case requires a key to unlock. Inside is a single skin drawn from the case's pool at the published rarity probabilities.

Drop rates per Valve's mandatory China-region probability disclosure: Mil-Spec ~79.92%, Restricted ~15.98%, Classified ~3.20%, Covert ~0.64%, and Rare Special (knives or gloves) ~0.26%. Within each rarity tier, every contained skin has equal probability of being selected. The skin is then assigned a random float value within its allowed range, determining its wear condition.

StatTrak™ has approximately a 10% probability on eligible drops, meaning roughly 1 in 10 unlocks of an eligible skin produces a StatTrak™ variant. Souvenir cases are awarded during major tournaments and follow different distribution mechanics — Souvenir variants of skins from the source map's collection are dropped at the case opening.
