For my backyard golf green, I wanted a flag cup that looked and felt like the ones on a real course. GST's Aluminum Flag Cup delivered. It's solid, weather-resistant, and gives off a satisfying sound when the ball drops in. Installation was simple, and it has stayed firmly in place ever since. This cup adds a level of professionalism to my home setup that I didn't think was possible. It's a small investment that makes a big difference.
