Our 30 mm static wisk brushes are 1-1/4in. wide and feature brush fibers
which are composed of a special blend of natural goat hair and soft,
conducive natural fibers. Dust is removed by the goat hair bristles, and
static is dissipated by the conductive fibers. The conductive fibers are
specially woven into a microfiber cloth, which makes the product extremely
effective. It will not lose its ability to remove static over time. They were
specifically designed to clean photographic images and optical surfaces.
