USP-S | Serum is a Classified pistol skin from The Arms Deal 2 Collection. It drops from the CS:GO Weapon Case 2. Its float range is 0.00 to 0.25, so it exists only in Factory New, Minimal Wear and Field-Tested. It is also available in StatTrak versions. Valve describes the finish as follows: “It has been painted in a digital pattern with metallic paints of various reflectivities over a chrome base coat.”
