GrassTex Perfect Putt Indoor/Outdoor Turf 15 ft. Wide

Manufactured to be used for indoor or outdoor putting greens. This performs best when sand filled and is designed to hold short chip shots while providing very true roll on putts. It must be installed over a firm surface (compacted limestone, traffic bond, concrete or asphalt), and then filled with usually 2-3 pounds of round dry sand per square foot.
