Well-Worn copies of this finish have floats from 0.38 to 0.45. In SteamWebAPI's snapshot of Oct 14, 2026, the lowest price on a marketplace with 3+ listings was $3.49 on Tradeit; 13 marketplaces listed it. The most recent Steam Community Market sale was $5.98.
The misunderstood middle child of the SMG family, the UMP45's small magazine is the only drawback to an otherwise versatile close-quarters automatic. This custom paint job is inspired by old animation cartoons.
