These 25 x Callaway ERC Soft Triple Track golf balls are an A/B Clearance Grade and are balls that have only been part graded and may have small signs of previous use with play/pen mark, but still have plenty of play life left in them. These popular golf balls from Callaway have the revolutionary Triple Track Technology that dramatically improves alignment, compared to the industry standard, i.e. the classic side stamp alignment aid. Great Value.
