Easy to use on hard surfaces: It can be difficult to put the golf tee into the ground when golfing on the driving range or course throughout the winter. So these were very useful at the time. Indoor practice anytime, anywhere: If you want to practice hitting the ball on the practice mat at any time of the year, this allows you to have t-shirts of different heights for that purpose. Save time: You don't have to wonder if you've reached the same height at the same time. You spend literally zero time adjusting the height of the tee, which does give you more contact with the ball. DURABLE: Made of durable rubber, the golf tee has a simple and classic design, perfect for hitting the ball. Durable and easy to carry. Application: Does not fly away when teeing off. Great for cold days and winters. This does the job perfectly, and the variety of sizes gives you options for each club. Color: red, blue, yellow.
