Yonex NS9900-LTD (purple) badminton racket is made of the same material as the ordinary version NS9900, using X-chain fullerene nanocarbon. This kind of material is a breakthrough in the history of badminton rackets, which plays a very important role in improving the delivery speed of rackets, and at the same time, it can increase the bounce of rackets by 5% and improve the stability by 15%.

Many top players prefer a solid feel, and the feeling expressed by "solid feel" is actually that the racket has a great impact at the moment of hitting the ball, and the vibration disappears quickly after hitting the ball. NS 9900 has good shock absorption effect, can quickly absorb external shock, has a firmer hitting feel, and reduces the power load of the batter's body by 20%. In addition, the NS 9900 racket handle is made of fullerene, which reduces the weight of the racket handle and improves the flexibility of the racket by 7%.

NS9900-LTD (green) badminton racket is a limited edition commemorative racket specially designed by YONEX for the 20 1 1 London World Championships, which is very collectible. The racket has changed the tone of the ordinary version, with purple as the main tone, giving people a bright feeling. The pattern of the racket continues the classic cross-woven pattern of NS9900, and the atmosphere remains the same! The racket frame is marked with the words "Yonex BWF World Champion London 20 1 1", which shows nobility!
