An optimal material composition (among other things thermoplastic polyurethane) guarantees seamless products and therefore this quality tournament ball can be played on almost all tables. This includes, among other things, match weight control and guarantees that a maximum deviation is only less than 0.1 g. This ensures a constant quality of this excellent tournament match ball. The same applies to the 100 % precise diameter and the unique grip (aggressive profile finish), which is produced in a complex special process at Robertson. This best possible surface finish guarantees professional play and allows almost all playing techniques.
