Acroforce 100 4UG6 This is a limited edition racket from Mizuno's BDSS. I purchased it in mid-February of this year and used it for about two weeks, a total of approximately 6 times. As shown in photos 10 and 11, the shape of the frame differs at the top and bottom. Because of this, it offers both repulsion and good shuttle hold. I believe this racket is suited for offensive players. There is a unique design in the string pattern. Currently, it is strung with Aerobite at 28 lbs. If you wish, I can ship it without cutting the strings. The original grip has been removed. Please feel free to comment if you have any questions! Price negotiation is possible.
