Yonex ArcSaber Z-Slash SP The serials are: shaft serial: 8702343 cone code : 200892SP Is this racquet legit?
looks fine to me... pbsi is just the name for the indonesian badminton association... they put that logo on a lot of SP coded rackets...
the PBSI logo shall be printed .... in your racquet looks like just a sticker above the Yonex sticker.
you should let us know where you got it and how much it costs. the photos are of such poor quality, it is impossible to identify any details.
