Littleton Lasers offers many different types of lasers and laser accessories. We currently carry a purple, a green, and a red laser. All three go at least 4 MILES and can be seen well during the day. They are 5mW and cannot cause permanant damage to your eyes. They can even be used to point out stars in the night sky! The purple laser actually produces heat from up to 50 feet away and activates glow in the dark material! Get yours today by calling 720 333 6415
