With constant feedback from professional as well as amateur players, the second generation of Butterfly THREE-STAR G40+ Balls displays major improvements in all aspects. The wall thickness and roundness have been optimized alongside the even hardness across the circumference, resulting in an even more constant bounce (as well as improved spin capabilities), providing the player with additional quality and safety in his or her game. All players currently suffering from the difference between plastic balls of different manufacturers will be happy to note the more subtle sound and lower bounce of the second generation BUTTERFLY G40+ balls. Completed by the durability and longevity, the Butterfly THREE-STAR G40+ Balls remains the first choice on the road to success.
