This product was featured on the golf program "Gear Saru." It's a convenient and excellent item highly praised by Hanamaru Hakata and Keisuke Okada. It's 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. High-grade product, with a diameter of approximately 12.5mm, slightly thicker. It has a double-layer structure for a soft feel. 1. Where do you hang your sub-bag on the cart? You don't have a designated spot, right? 2. Are you hanging it in a strange place and bothering others? 3. Doesn't it get scratched by rubbing against the cart tires? 4. Where do you practice putting 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. You can practice quickly and effectively when you don't have time before the start. 8. It's cheap & convenient & with this, your score today will be great, of course! 9. This product was developed by myself, a golf enthusiast. 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 available: mandarin orange. Color variations and budget-friendly types are also available in my other listings. Please check the images, etc., and refer to them.
