The drop tiers follow Valve's standard distribution — Mil-Spec at 79.92%, Restricted at 15.98%, Classified at 3.20%, Covert at 0.64%, with a 0.26% chance of a rare special item (knife or gloves where applicable).

Sealed copies of the case itself are tradable on the open market — tracked across 13 marketplaces, ranging from $641.99 to $12,000.00.
