The Laser Wand Mandala Pointers, available in Green or Red, are perfect for festivals on the playa, dance parties, night clubs, any dark rooms, and for projecting onto landscapes to create a "firefly" effect. Aim beams into fog or haze to display bands of light as the full length of each beam becomes illuminated. Uses two AAA batteries and turns on by holding down the button on the side. We recommend carrying spare batteries for use during parties or events.
