This colorful Mid Century lighted electric Christmas tree top is a rosette halo of fiber optic strands with a circle of ten colored lights behind it. The strands are plastic but look like spun glass. It's about 6-3/4 inches diameter and in excellent working condition. The original box has some storage wear and is missing the cellophane window. Made in Japan for Doubl-Glo Paper Novelty in 1970.
