Your probably thinking... "What in the heck is a crystal ball?" well we are here to show you! A Crystal Ball is a K9 crystal made glass that usually contains engravings of a particular thing inside. One example is our well known solar system crystal ball which engraves all eight of our planets in a linear 3D perspective. It comes in sizes 60MM, 80MM, & a whooping 100MM as our biggest size. This resembles an awesome great idea because it is number one unique and has custom engravings that bring about a wow factor!
