Abstract: The light conductive optic fiber pompon of the invention consists of a plurality of acrylic filaments, blended with optic fibers, or added with the gold threads. After heat treatment, it becomes a semi-circular and round ball type pompon. A bowl is attached to the bottom of the pompon with hidden luminary (such as LED). When the luminary emits the light being therefore transferred to the tip of the optic fiber to produce twinkles. The light color of pompon varies with the color of the luminary to make the pompon a fancy, beautiful luminescent ornament.
