The FBC Mailbox is a surreal, brutalist-inspired object with a geometric, rectangular shape, featuring sharp angles and a monolithic presence. Its surface is smooth with a slightly weathered texture, suggesting age and use within the Federal Bureau of Control's environment. The mailbox is predominantly dark gray with subtle metallic sheen, accented by glowing red seams that pulse faintly, hinting at its paranormal properties. A small, asymmetrically placed slot for mail is present, surrounded by intricate, engraved symbols that seem to shift when viewed from different angles.
