Nippon Shaft VULCANUS V520 1W Callaway Sleeve Purchase Price: ¥25,000 I purchased this here. I think this is for 200-yard drives, for someone who currently drives 180 yards. Only test-hit at the driving range. The product name "Nippon Shaft VULCANUS" likely refers to the golf shaft product "VULCANUS" by Nippon Shaft. "VULCANUS" is a distance-focused carbon shaft for drivers, primarily developed to address the issue of insufficient distance for amateur golfers with head speeds of 43 m/s or less. Thank you for viewing.
