A small, cylindrical vial with a retro-futuristic design, featuring a metallic cap and a glass body containing a glowing, luminescent blue liquid. The vial is labeled with weathered, faded text indicating its purpose, and the glass has subtle scratches and wear marks from post-apocalyptic use. The design is functional yet slightly ornate, with embossed details on the metallic parts reflecting its 1950s-inspired aesthetic.
