GST’s Aluminum Flag Cup added the perfect touch of authenticity to our backyard putting setup. The build quality is excellent-it feels sturdy, looks sharp, and hasn't rusted or discolored even after exposure to the elements. It fits perfectly into the turf cutout and gives our green a clean, finished appearance. Practicing at home now feels like being at a real golf course. This is a must-have if you want your putting green to feel official.
