The Star Galaxy Multibeam Green Laser Pointer puts those single-dot pointers to shame! A push of the button projects a a dazzling galaxy full of points of light. Just turn the dial at the end of the laser and like a kaleidoscope, the points start moving around for a trippy prism-like effect that will astonish onlookers. The 532 nm green laser wavelength is about 50 times brighter than a red laser pointer! Comes in a beautiful felt-lined presentation/storage box that is perfect for gift-giving! Uses 2 replaceable AAA batteries (included).
