The entire body of the submachine gun is covered with a colorful design inspired by old cartoons. The composition consists of numerous small details, including a row of cartridges and a boxing glove pushing one of them. The design is also complemented by stylized indicators, switches, symbols, and markings. The color scheme is dominated by blue, pink, and yellow shades. All elements have dark outlines, emphasizing the cartoon style.
The skin's Float Value ranges from 0.00 to 1.00, which makes UMP-45 | K.O. Factory available in all exterior conditions. The first minor abrasions appear on various parts of the body in Minimal Wear condition. They become clearly noticeable at approximately 0.35. As the Float Value grows, abrasions increase in number and size. At the highest wear levels, the body is covered with significant abrasions, and the skin becomes noticeably darker.
