High-grade product, approximately 12.5mm in diameter, slightly thicker. Double-layered construction for a soft feel. This is a holder for hanging a sub-bag on a golf cart. It can also be used as a putting practice guide, with a width of approximately 108mm. The outer material is urethane, so it won't scratch your bag. This product was featured on the golf program "Gear Saru." Hakata Hanaru and Keisuke Okada highly praised this convenient and excellent item. 1. Where do you hang your sub-bag on the cart? You don't have a good place, right? 2. Are you hanging it in a strange place and bothering others, making them dislike you? 3. Doesn't it get scratched from rubbing against the cart tires? 4. Where do you practice if the green is crowded before the start? 5. The width is almost the same as the cup diameter, and some golf courses don't have the cup cut out. 6. With this, you can place it anywhere and practice putting. 7. When you don't have time before the start, you can practice quickly and effectively. 8. Cheap & convenient & with this, your score today will definitely be good, right? 9. This product was developed by a golf enthusiast, myself. 10. Even if stepped on, the core is made of soft iron metal, so it can be bent and corrected. 11. Of course, it won't break even if you throw it around. 12. Not a product made in China. Reliable and safe, made in Ibaraki Prefecture, Japan. The outer material has "made in Japan" and manufacturer logo warnings displayed in some places. Other colors are cobalt blue and yellow magic. Color versions and budget-friendly types are also available in my listings. Please check the images, etc., and use them as a reference.
