Polaris 200m string reel

Matteo Berrettini has been playing with the Signum Pro Firestorm for a long time. Since he has been very successful with it, Signum Pro has decided to make a new string that is very close to the Firestorm, but has improved some features. With the new Signum Pro Polaris you can give your game a little more power, striking in a fresh neon yellow. The string is available in 4 diameters.
