Butterfly Dignics 09c Table Tennis Rubber With a sticky surface, DIGNICS 09c offers immense friction and grip leading to high spin value and a curved trajectory during topspin if sufficient power is generated to impact the 44? hard Spring Sponge X. The requirement in power, along with the comparatively low speed makes DIGNICS 09c a choice for players of higher skill range and ambition, looking for the benefits of a sticky rubber. In order to protect the sticky surface, DIGNICS 09c comes with a pre-applied protective foil.
