Balls

Gaze into these crystal balls and you may not see the future, but you will see refracted light beaming out magically.  Excellent for arts & crafts hobbiests looking to add a magical element to their designs.  Gandolf the wizard is a big customer here, he always has these on hand in his magicians workshop.  Merlin is also a huge fan.  They both buy in bulk to be sure they never run out of glass crystal balls.
