The Stun Bomb is a compact, cylindrical device with a matte black metal casing, featuring subtle wear and tear indicative of frequent use in harsh environments. It has a prominent red activation button on top, surrounded by a grooved texture for better grip, and a small LED indicator that glows faintly when armed. The base is slightly wider to ensure stability when placed, with visible seams and screws suggesting it's handcrafted from scavenged parts.
