Our Hollywood clapboard pins are perfect party favors for film festivals, Oscar parties, and any other Hollywood-themed events. Each of our light up Hollywood clapboard blinkies has 4 LEDs, 2 red and 2 blue, so the lights will shine as brightly as they do on the Sunset Strip! Use the butterfly connector on the back of your Hollywood clapboard pins to attach them to practically anything and let the flashing fun last all night. Please note the butterfly connector may create a small hole in the garment you attach it to. These light up Hollywood clapboard blinkies come with CR927 batteries included and installed and the batteries are replaceable for nonstop flashing fun! Our Flashing Hollywood Clapboard LED Blinkies are sold by the dozen and come individually packaged in a clamshell.
