The StarPro Greens patented putting cup works like a real golf hole without having to core a hole in the floor! When the golf ball enters the putting cup, the Starball on the flag absorbs the golf ball's energy, allowing a correctly hit ball to stay in. The Starball cup is 4 1/4" regulation size and 3/8" deep. It's perfect for indoor play and outdoor/patio/poolside use. Two per order. Pat. No. 6,287,213.
