How much is the key?
$2.49 in the in-game store. Keys cannot be bought on the market or traded: the price is the same for everyone.
Is the Prisma Case worth opening?
No by expected value: $2.33 back per $3.85 opening, or 61% of the cost. Treat opening as entertainment, not as a way to acquire skins.
Will the Prisma Case be discontinued?
It already rotated out of the active pool (rare pool as of our Apr 12, 2026 registry snapshot). It still drops rarely — cases never leave the game entirely. Drop-pool registry →
How do I get one without opening it?
Buying it is the practical route — from $1.23 across the markets in the table above. It no longer drops weekly.
Is opening cases legal in my country?
Loot-box rules differ by country: Belgium treats paid loot boxes as gambling and Valve disabled case opening there, while several other countries require odds disclosure or age gates. If opening is restricted where you live, buying items directly stays available. Responsible trading guide →
