BlueGrip is the first rubber sheet which has a Chinese style sticky top sheet in combination with a blue sponge with inbuilt speed glue effect. BlueGrip combines the best of two worlds – and made in Germany.
 
The DONIC BlueGrip R1 has a slightly softer feel and helps to compensate for the loss of spin that the plastic ball has entailed.
