This is a torque wrench for Mizuno golf clubs, equipped with the Quick Switch System. It was included when I purchased the JPX Elll sv driver, but I never used the wrench because I used the default loft and lie angles. 【Specifications】 ・Name: Mizuno Golf Club Dedicated Torque Wrench ・Materials: ABS, Chrome Vanadium Steel ・Part Number: 5KJLW80000 ・Retail Price: ¥2,200 (tax included) 【Compatible Clubs】 ・ST-MAX 230 Driver ・ST-MAX 230 Fairway Wood ・ST-MAX 230 Utility ・ST-X 230 Driver ・ST-Z 230 Driver ・ST-Z 230 Fairway Wood ・ST-Z 230 Utility ・ST-X 220 Driver ・ST-Z 220 Driver ・ST-G Driver ・ST-G Fairway Wood ・ST-G 220 Driver ・Mizuno Pro MODEL-E Driver ・Mizuno Pro Fairway Wood ・Mizuno Pro Utility ・JPX850 Driver ・JPX900 Driver ・JPX Elll sv Driver ・MP TYPE-1/TYPE-2 Driver ・ST-200 Driver ・ST-200X Driver Ships via Rakuraku Mercari. ※Please note that "reserved listings (hold)" are no longer available as of June 2024. ※Please understand that returns are not accepted to prevent swapping, etc.
