This patented putting cup insert is included with the purchase of all of our putting greens. It 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 stay in. The Starball cup is 4 1/4" regulation size and 3/8" deep. Perfect for indoor play and outdoor/patio/poolside use!
