Genuine Lost Ball Yellow, 20 balls, mixed years and types. Grades are a mix of A and B, with slightly less than half (7-8 balls) being A-grade. Lost balls are used balls. Please purchase only if you understand this. m(_ _)m Regarding the grades of the lost balls I am selling, they are as follows: A-grade = Hand-washed and inspected, with no noticeable scratches, and no marker marks, logos, or fading; they are in very clean condition. B-grade = Hand-washed and inspected, with some scratches, marker marks, logos, or names mixed in, but still usable on the course. C-grade = All balls have dirt, some noticeable scratches, marker marks, logos, or fading. Recommended for practice balls.
