I received a box containing an unfamiliar item sent from the Dark Web

The package arrived in a plain brown box with no return address, wrapped tightly in heavy black tape. Inside, resting on a layer of dense charcoal foam, was an unmarked metallic object that felt unnaturally cold to the touch. It carried no brand name, serial number, or user manual—just a stark warning label indicating it was dispatched through an underground Dark Web distribution network.
