The Derbystar Classic TT II is our best-selling model. The ball is perfect to use as a match and training ball. The ball is made of durable PU material, which feels like leather but does not have the downsides of leather. There is a 3D diamond structure on the entire material surface, which ensures excellent, stable flight characteristics. The ball is available in three different sizes: size 3 (335 grams), size 4 (365 grams) and size 5 (430 grams). Size 5 is also available in three different designs. Thanks to the different designs, balls from different teams can be hold apart.
