Polaris 200 m rope spool

Matteo Berrettini has been playing with Signum Pro Firestorm for a long time. Given its great success, Signum Pro decided to make a new string very similar to the Firestorm, but with some improved features. With the new Signum Pro Polaris, you can add a little more power to your game, hitting in a fresh neon yellow. The string is available in 4 diameters.
