This is a genuine racket sourced through official channels. It is not a counterfeit product. We cannot offer discounts. Negotiation requests, including those for bundled purchases, will be blocked. For multiple purchases, we offer a ¥800 discount on the second set and subsequent sets. (If a set of two is already listed, it has already been discounted, so this applies to additional purchases.) A warranty card and a soft case are included. We can string the racket for an additional ¥1,500. We use a YONEX electric stringing machine. If you wish to have it strung, please comment before purchasing. There are reports that the original grip may peel off with the nylon grip tape when removed for this model number. We have received an extra grip tape from the manufacturer, which we will include. Please consider purchasing only if you understand this.
