5mW 532nm Green Laser Pointer Light Pen High Power Bright Beam for Stargazing

Description These laser pointers are both entertaining and useful. This is a 5mW high power laser that will offer a much brighter beam than most laser pointers. Just add two AAA batteries (not included) and you'll be set for hours of laser light beam emission. Green is the perceptively brightest color, it's so bright that you'll be able to see the beam cutting through the air when the lights are out. Take it outside at night for an enchanting stargazing experience. The intense bright light is not without drawbacks however, prolonged exposure even to refracted laser light can damage eyes and direct exposure can quickly cause blindness. Warning: Laser light can cause permanent damage to eyes. Never shine laser light in the eyes of people or pets.
