English information from manufacturer:

The Silver 3K is a padel racket from the new Side Spin 2022 collection made for players looking to raise the level and speed of their game. With its teardrop shape, the sweet spot is slightly higher than a round racket (Silver ctrl). That is why, together with the 3K carbon, they will help you have greater power in the smash and increase the speed of all the high balls.
We innovate with metal technology, which are metal sheets around the frame, this technology allows us to give the frame greater rigidity
The Silver is helped by the black medium Eva to correct perfectly and offer a high-level balance to the racket. Features a sandy finish, that gives an extra grip.
