This is a Carbite putter (ZG model). The sole is stamped with "US PAT 5669825 / 4768787" and the head face has the letters "ZG". There are overall scuffs and scratches from use (please check the photos). The grip is cracked due to aging, so replacement is recommended. Please refrain from bidding if you are sensitive to the condition, as this is a used golf club. This item is being sold as is. *All photos are included. *No claims or returns accepted. 9308
