This is a shell of "Mirage Billiard Balls by JL" set.
The quality of these billiard balls is getting rave reviews from the magic world.
These billiard balls are made from silicone material similar to the kind that is used for surgery.
So these billiard balls should not fade and can be used as semi-permanent.
