About the Nova | Koi
Nova | Koi is a Restricted skin that drops from one of the 42 CS2 weapon cases, the Operation Breakout Weapon Case.
Valve released the Operation Breakout Weapon Case on 1 July 2014.
Each open has a 3.9950% chance (about 1 in 25) of pulling it, as one of 4 Restricted finishes. One in ten of those drops is StatTrak.
It sits in tier 2 of 5 (Mil-Spec to Rare Special) and ranks #22 of 27 finishes in the Operation Breakout Weapon Case by top-wear Steam price.
Its Steam price runs from $2.82 to $3.69 across wears, against $13.26 to open the Operation Breakout Weapon Case (case plus $2.50 key), so even its best wear is worth less than one open.
