Check out this latest design in our Custom Bowling Ball line of products. This is one of the many stock image bowling balls that are available. Custom stock image bowling balls take 2-3 weeks for production and shipping. These are made of a polyester material. The image is actually embedded in the surface of the bowling ball and does not wear off over time. These bowling balls are perfect for the recreational bowler, bowlers who prefer to throw the ball straight and competitive bowlers for shooting spares at those pesky corner pins.
