1) they should be real. 2) the place is not authorized Yonex retailer 3) the racquet is most likely SP coded. 4) ask if you get 1 year warranty.
I dont know, I would'nt consider buying unless I did it up front in person.. 130 USD for a NS9900.. I have my doubts..
i would request actual pictures and ask specifically when you purchase a racket you'll get the one with the code in the picture.
