UMP-45 | Gold Bismuth
A Restricted UMP-45 skin from The Operation Broken Fang Collection, the UMP-45 | Gold Bismuth is also available from the Operation Broken Fang Case, with StatTrak as an option. Its finish sandwiches a gold bismuth crystalline pattern between white and black base coats, producing an iridescent, mineralogical appearance across the submachine gun's surface. The float range stops at 0.7, keeping the skin within Factory New through Well-Worn territory. As wear increases toward that ceiling, the layered white and black coats begin to chip, gradually exposing the underlying base and altering the color balance.
