How the Winter Offensive Weapon Case drops and opens
Winter Offensive Weapon Case, first sold Dec 18, 2013, has rotated out of the active weekly pool: it now drops only from the rare pool at a sharply reduced rate, so most copies on the market are old stock changing hands — currently from $9.07 across 23 marketplaces. Retired cases tend to appreciate as that stock thins out; the dated pool history is in the drop-pool registry. Drop-pool registry →
A $2.49 store key is mandatory per opening (keys left the market in 2019), and the case itself typically costs less bought outright than farmed. The economics: $12.32 in, $6.44 expected out, 52% average return before fees. Anyone hunting one skin should buy it directly — the tiles above link each item to its markets.
