Well then from my exp, there is a stamp sticked at the grip-end, scratch it and go online to check at kason.com.cn or something whether the racquet is genuine
Hey everyone, I got my hands on the C7 and F9 (Toronto, Ontario, Canada). For those interested in trying them out, let me know and we can setup a time to meet at a badminton club to hack around. Please don't PM me - email me at sTRINHgs@gmail.com Thanks!
To those who are trying this, DO NOT use a coin to scratch the label. It will most likely damage the label. It would be better to use your fingernails and apply just some force when scratching it.
Good point! Try to do this before using the racquet as well because I tried to scratch it off after playing with the racquet but my sweat and pressure from holding the handle messed up the label big time!
