is this only possible from the serial numbers on the reverse side of the rac where the ?U?G is displayed?

other than that?

If you are not sure about it, you can always bring it to the closest Yonex Dealer and have them to inspect it for you.


Or post pictures (detailed) in here will also do it :D

Or just buy the racquet from an authorized Yonex dealer to begin with. :p

Also, if u get an offer like only 10% of the price should be, never think you hit the jackpot today. ;)
