This choker necklace has a cool ridged diamond-like pattern that makes it also look a bit gothic. Internal bright multi-color LEDs flash throughout. 16" length means it sits close to the neck like a collar. 2 snap buttons allow you to adjust the length. The plastic of this necklace comes in assorted translucent colors with a slight metallic glitter effect (sorry, no individual choice of color). All feature the same multi-color LEDs.
