Released in September 2015 via the Shadow Case, the MAG-7 | Cobalt Core sits at the Mil-Spec tier within The Shadow Collection.

The float range for this finish is restricted to 0.00–0.50, so Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for MAG-7 | Cobalt Core are tracked across 17 marketplaces, with prices spanning $0.20 to $4.06 depending on wear, variant, and seller.
