A X-Blem bowling ball from SPI Bowling Products (Storm, Roto Grip, and 900 Global) will have an X stamped by the serial number. X-Blems are seconds due to a cosmetic blemish similar to an X-Comp, but the specifications fall out of the 2-4" & 2-4oz. range. The reaction of the bowling ball will be the same as the first-quality ball.
