Atomic star cardigan clips in glow in the dark light blue and gray. Stars are made from a lightweight resin with iridescent blue glitter added. Beaded chain is made from 10 mm bayberry beads in gray, and extends 7", with an overall length of 9.5" total from outer edges of stars. Each star has 2 tie tack pins attached to the back and measure 1.5" at the tallest point. Glow in the dark photo was taken after being exposed to a uv light for 5 seconds, but also works under regular lighting as well.
