Developed by the popular retailer Costco, Kirkland golf balls are known for their high quality and affordable prices relative to other premium brands. Despite their lower price point, Kirkland golf balls by Costco deliver great performance. Their most popular ball, the Kirkland Signature, has a three-piece design with a urethane cover that provides great spin control and a soft feel. At LostGolfBalls, we offer premium used Kirkland golf balls. Sourced from premier courses around the country, each ball is thoroughly cleaned and inspected to determine its condition. The top condition we offer, Mint (5A), looks, feels, and plays just like a new ball. Order Kirkland balls today and enjoy free and fast shipping plus a 30-day free return guarantee if you're not satisfied with your purchase.
