Genuine Yonex Korea Product, Used for a Week, Like New, Kaiza Light 4S, Kim Hyo-joo Winning Specs

I received a fitting at the Yonex Korea official fitting center on May 30th, and this is in like-new condition, having been used for one round of golf and one simulator session. I tested shafts of all specs from 3s to 4s and ultimately chose the 4s because it provided the most distance and a heavy feel. However, I feel I need to switch to the more comfortable 3s now, so I am selling this to someone who needs it while it is still in like-new condition! Since I only used it for a week, you can consider the warranty fully intact. Please do not compare it to the direct import parallel products sold cheaply online, as there is a significant quality difference compared to the genuine product. Based on my experience, using genuine products is better for your mental health!! The grip is a caviar grip and is practically brand new. The sleeve is TaylorMade! If you need a replacement for a sleeve from another brand, the fitting shop where you purchased it will exchange it for free. Those who have used Ventus or similar-grade 5s shafts will definitely feel the difference in distance and find this incredibly comfortable. Those using stock shafts will likely experience a whole new world. The length is the standard size of 45.5 inches.
