I installed a putting green for a client who wanted the complete golf experience, so we used the Plastic Flag Cup from GST. It's durable and fits perfectly within the turf. The cup has a professional look and feel, enhancing the overall appearance of the green. Despite being plastic, it has held up remarkably well against the elements and daily use. My client was thrilled with how it turned out, and they use the green almost every day. This is a high-quality product for anyone looking to complete their putting green setup.
