LOVE Tennis Racket Heart Vibration Dampener is a small accessory that is attached to the strings of a tennis racket to reduce the vibrations generated during ball impact. These dampeners are designed to absorb and dissipate the energy that is transmitted from the ball to the racket upon contact, which in turn helps to minimize the vibrations that travel through the racket frame and handle to the player's hand. It also makes your racket look super cute!
