American Club A.M.C CRAFT ACE UL63 shaft. This is an iron (5-iron or low center of gravity model) from the "LOW C.O.G DESIGN" series by the Power Play brand. Manufacturer: Power Play Features: Low center of gravity (Low C.O.G - Center of Gravity) design for easy ball launch. Application: Golf iron club. *Quoted from the internet. This is the 4-iron and sand wedge I used previously. Although the numbers are different, I'm selling them as a set. The grip on the sand wedge was changed a few years ago. The grip on the 4-iron is over a decade old, so please assume it needs to be replaced.
