English information from manufacturer:

The NERBO WPT 2022 retains all the character of its predecessor: powerful, solid and fast. With its new Multilayered Black Eva core, an evolution of the Multilayered Core that, together with the 18K carbon faces, allows an optimal distribution of the energy generated in hitting both low speed and power strokes, thus improving the performance in the game.
In the NERBO WPT 2022 we've spoiled you with the smallest of details: rough surfaces to maximize effects, lateral anti-vibrators built into the racket structure and a careful core design
It includes the new Smartstrap® replaceable safety strap system. It improves the hygiene and safety of your racket by easily replacing the strap without losing the guarantee as it isn´t necessary to tamper with the bottom cap.
