Opening the Prisma Case requires the case itself (~$1.20) plus a key ($2.49 on Steam). The total cost is approximately $3.69. Most openings return Mil-Spec or Industrial skins worth less than the opening cost, but rare Covert or knife drops can be worth many times more.

Statistically, no: based on Valve's drop odds and live prices across 40+ marketplaces, one Prisma Case opening costs $3.69 (case + key) and returns $2.27 in expected value — an expected return of -38.4%. Rare drops are why people open anyway: the top Covert skin (M4A4 | The Emperor) is worth ~$241.28. See the Unboxing Odds & ROI section above for the full breakdown.
