A long drape scarf in deep obsidian with a woven Mirrorline thread that creates a faint reflective sheen — shifting from matte to luminous as the wearer moves. The fabric is woven with passive signal-dampening threads that block ambient BCI broadcast bleed, offering a narrow privacy buffer in crowded boardrooms. Width is generous enough to function as a shoulder wrap, and one end is weighted with a single cast-iron bead in a brushed bronze casing.
