Tinarc 5 with softer sponge. TinArc 5 combines both great feeling with elasticity allowing for powerful stroke execution. TinArc 5 rubber allows the ball to rebound rapidly with a soft sponge and a highly elastic topsheet, ideal for feel with quick loops, ball handling near the net, or off-court play. This outstanding elastic rubber with thicker pimple design beneath the topsheet enables strong power with minimal effort. The new sponge also uses MACRO-CELL & High-Elasticity Particle Osmosis technology, providing powerful attacking capabilities. TinArc 5 is specially designed to enhance the speed of 40+ celluloid-free T.T. balls and is suitable for continuous offensive play.
