Manufacturers release their high performance bowling balls under the X-Blem, X-Out or Second label when small non-performance issues occur. The core and coverstock combinations on these bowling balls are identical to the first line bowling balls.A bolwing ball is labeled an X-Blem, X-Out, or Second for any one of the following reasons:
Color pigmentation
Small pitting caused by air bubbles.
Unique pin placement, top weight, or mass bias marking location.
Labels are engraved in unusual places or may have the wrong logos engraved on ball.
Swirl patterns of the ball are not consistent, which may effect the color (look) of the ball greatly.
Engravings such as the serial numbers, cg location markers or logos may be stamped on the ball more than once
