Putting Cup Rings - Set/18

Providing spectacular, enhanced hole visibility, they accelerate play on the green, all but eliminating pin tending, and increase tee-time capacity by 10-15%. They also stabilize soil around the top of the hole, preventing erosion and desiccation, and seal in moisture for the grass roots. Flexible, economical and reusable (6-8 weeks average). Approved by the US Golf Association for "Official USGA Handicaps."
