What is a fushigi ball made of?

I don't know exactly, but my guess is that it's either: 1. materials made together to do what it does or 2. its a new type of material. I don't know but its my guess. I just hope theirs better answers than this.

FUSHIGI IS A PATENT PENDING DESIGN AND IS THE WORLDS ONLY BALL IN A BALL CJ BALL THAT IS SAFE FOR KIDS AND ADULTS ALIKE, BEWARE OF PURCHASING TOTAL CLEAR ACRYLICS BECAUSE THEY ARE LIKE MAGNIFYING GLASSES. FUSHIGI IS MADE OF CHROME AND ACRYLIC. NOT GLASS, NOT SOME MYSTERY MATERIAL, IT WONT BREAK OR SHATTER IF DROPPED,,,

IF ITS NOT A "FUSHIGI" BE VERY CAREFUL BUYER BEWARE....

^ Wrong, it's a mirror in a plastic ball.
