About the MP9 | Deadly Poison
MP9 | Deadly Poison is a Mil-Spec skin that drops from one of the 42 CS2 weapon cases, the Chroma Case.
Valve released the Chroma Case on 8 January 2015.
Each open has a 15.9840% chance (about 1 in 6) of pulling it, as one of 5 Mil-Spec finishes. One in ten of those drops is StatTrak.
It sits in tier 1 of 5 (Mil-Spec to Rare Special) and ranks #38 of 44 finishes in the Chroma Case by top-wear Steam price.
Its Steam price runs from $0.59 to $10.27 across wears, against $9.20 to open the Chroma Case (case plus $2.50 key), so 1 of its 5 priced wears are worth more than one open.
