Tec-9 | Perimeter was added to the game on July 8, 2026, as part of The Spy Tech Collection, released with the Season 5, Armory, and More update. The skin was created by Kuch. Kuch previously worked on Dual Berettas | Melondrama, which was also accepted into the game.
Most of the pistol's metal body is unpainted. The receiver and grip are decorated with an abstract pattern of small crosses, squares, and dots in gray and pale orange. Above the magazine is an image of a perspective grid that looks like a tunnel extending into the distance. The rear part of the receiver features a geometric pattern made of vertical stripes.
The skin's Float Value ranges from 0.00 to 1.00, which makes Tec-9 | Perimeter available in all exterior conditions. At approximately 0.15, the unpainted metal parts begin to develop a warm tint. As the Float Value rises, this effect becomes more noticeable, while the gray elements of the pattern gradually wear away. The pale orange details become darker but remain visible. At the highest wear levels, the metal parts are covered with a layer of rusty-orange patina.
The pattern index does not affect the skin's appearance.
The quality of Tec-9 | Perimeter is Industrial Grade. The skin is not available in a StatTrak version.
