This is the VICTOR AURA SPEED (4UG5) racket. It's a highly-rated racket. It's famous for being used by men's doubles world number one player Goh Sze Fei, as well as women's doubles top player Lee So-hee (South Korea), and Japanese women's doubles player Nakanishi. The strings are Exbolt 65 at 25lbs. I'm selling it because the feel when holding and swinging it without the grip wrap was different from what I expected, so I haven't used it. I selected this one from the store's stock, choosing a head-heavy model. The racket case, warranty card, and the original grip are included. Thank you.
