The tunnel star necklace takes the popular infinity tunnel mirror effect and enhances it by shining the LEDs through the translucent star. The mirrored surface makes the 6 red, green, and blue LEDs seem to repeat over and over into infinity for the coolest effect. Choose from 6 selectable modes: all flashing, slow color-changing, all continuously on, red flashing, green flashing, and blue flashing modes. Uses 2 super-strong CR-2032 lithium batteries (included and replaceable) which last over 12 hours of use before needing to be replaced. The tunnel star measures approx. 3.5" wide. A black cord necklace is included.
