THE TOURNAMENT STRING FOR MORE SPIN AND CONTROL!!
MADE IN GERMANY!
The rough version of the Big Star Potenza is a high-quality co-polyester stringthat has been made using the innovative nature of Nature Peel Technology (NPT), a nature-inspired specialty process.
The NPT makes it possible to make tennis strings with a ROUGH SURFACE (like the orange peel):
This surface ensures that the string "bites" into the ball and you generate more spin (topspin or slice) than traditional strings.
