20 mW Green Laser with Starburst Filter

These brilliant lasers give a brilliant green dot, with a beam that is visible during the day as long as you are inside the house. So you can imagine the intensity of this laser at night! The awesome Starburst Filter that comes with it is very fun to experiment with. As you turn it, it gives different patterns of dots and lines from the floor up to the ceiling! Or just take the filter off and you have a powerful green dot for the laser pointer.
