Looking for more durable practice green cups? Standard Golf just introduced the first and only Aluminum practice green cup, and coated it with an exclusive Bonderite™ powder coat process, the most chip resistant powder coat in the business. In addition, a new beveled edge bottom makes it much easier to insert and remove. Dimensions of the new cup are 4"H (10 cm) x 4 1/4"D (10.8 cm).
