Selling these golf balls because I'm changing my preferred ball type, and I don't want them to go to waste. One dozen is unopened. The remaining balls are number 1, 2, 3, and 4, with two of each, totaling 8 balls. High-performance 3-piece urethane cover golf balls from Costco, Kirkland brand. 20 unused balls.
