Glow in the Dark Crystal Ball
These rough finish, porous stone spheres glow with the most beautiful blue hue versus the traditional green that is most often associated with glow-in-the-dark items. At approximately 35mm they fit well in the palm of your hand. Their rough finish makes them less susceptible to scratching, making them a nice gift for children as well. Each glow ball comes with a base to keep it from rolling around.
