The FBC Mail Conveyor is a sleek, industrial-grade conveyor system designed with a brutalist aesthetic, featuring angular metal frames and segmented rubber belts. Its surface is weathered with visible scratches and dents, suggesting heavy use within the Federal Bureau of Control. The conveyor's mechanical parts are exposed, showcasing intricate gears and pistons with a matte black finish, while the belts have a slightly glossy, textured surface to prevent mail slippage. Subtle glowing blue accents line the edges, indicating its integration with the Oldest House's paranormal energy systems.
