A never-used set of 15 Glo Star transparent Lucite acrylic plastic 5-point star reflectors for both C6 and C-7 type (standard bulb) Christmas light strings. They're about 2-3/4 inches diameter and look great when the tree is lit up. The star reflectors are mint on the original unopened card.
Oddly, there is no manufacturer's name on the package. I know the stars were first produced in 1949 and originally sold under the StarBright name, then Glolite (division of Noma). The colors in my photo turned out poorly due to bad lighting - the stars are standard red, green, blue, orange, and clear - three of each.
