The Rasanter series launched in March 2017 is the latest innovation by andro. The Rasanter R47 has been designed for the 40+ plastic ball. The thick sponge of the Rasanter compensates for the spin differences with the 40+ ball. The R37 has a 37° sponge developed for high level players. This hardness in sponge provides extra power and speed. This rubber caters for mid to advanced players from various placements on the table. The sponge softness allows for huge amounts of spin and control.
