Polaris 200m String Reel

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