About the Tec-9 | Isaac
Tec-9 | Isaac is a Mil-Spec skin that drops from one of the 42 CS2 weapon cases, the Huntsman Weapon Case.
Valve released the Huntsman Weapon Case on 1 May 2014.
Each open has a 13.3200% chance (about 1 in 8) of pulling it, as one of 6 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 #19 of 28 finishes in the Huntsman Weapon Case by top-wear Steam price.
Its Steam price runs from $2.64 to $25.44 across wears, against $13.96 to open the Huntsman Weapon Case (case plus $2.50 key), so 1 of its 5 priced wears are worth more than one open.
