This very retro 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. A packaged replacement light bulb is included. The original box is in good condition with a partially loose cellophane window. Made in Japan for Doubl-Glo in 1970.
