High-grade product, approximately 12.5mm in diameter, slightly thicker. Features a double-layer structure 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." It's a convenient and excellent product highly praised by Hakatakawamaru and Keisuke Okada. 1. Where do you hang your sub-bag on the cart? Nowhere, 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 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. Cheap & convenient & with this, your score today will be great, of course! 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 Type 2, Yellow Magic Type 2, and Orange Type 2 color versions, and also budget-friendly types are available.
