UMP-45 | Exposure
Available from the Spectrum 2 Case as part of The Spectrum 2 Collection, the UMP-45 | Exposure is a Restricted skin with StatTrak available. Its custom paint job resembles an x-ray image, complete with a rib cage motif rendered across the weapon's surface, producing a striking medical-themed aesthetic unusual for a submachine gun. The float range tops out at 0.55, so the skin never appears beyond Field-Tested wear. At low floats the x-ray detail is crisp and legible; as wear climbs toward the cap, surface degradation softens the fine structural lines of the design.
Cheapest wear we have on this page. Pattern / float overpay is extra.
