The FBC Mail Bag is a medium-sized, utilitarian bag with a brutalist design, featuring a rigid, angular structure made from a durable, dark gray fabric with a slightly weathered texture. It has a prominent Federal Bureau of Control logo embossed on the front, with metallic accents on the zippers and buckles that contrast against the muted fabric. The bag includes multiple compartments, each with a distinct, geometric shape, and the main compartment is secured with a heavy-duty zipper that has a subtle, luminous glow under certain lighting conditions, hinting at its paranormal properties.
