LOKI Thor TELSON 100 Red 2.1mm Hardness 47.5 degrees This rubber is used by Zhou Yu on his backhand. It was used for two months, two hours a week, on a Fan Zhendong ALC blade (size: 157 x 150mm). It still has plenty of grip. I don't think there are any noticeable scratches, but please check the photos. The package is not included due to the size.
