It is extremely thin at only 0. 63mm, but is far more durable than other badminton strings within the same diameter. The thin strings offer superior repulsion, control, and feel. Due to the thin string, the hitting sound is also excellent without needing to install it at a high tension. Specification Core Material: High intensity multifilament nylon
