UMP-45 | Gold Bismuth is a Restricted SMG skin from The Operation Broken Fang Collection, which entered the CS2 economy alongside the Operation Broken Fang Case in October 2020.

The float range for this finish is restricted to 0.00–0.70, 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.
