This is a carbon fiber keiryu rod. It has been used. The fourth section is damaged and has been replaced with one of the same size. Please check photos 1-3. Even after the replacement, I have caught Yamame and Iwana without any problems. There is no worry of it coming loose. It stops at the marked point. Please check photo 3. How about it as a sub rod? We appreciate your understanding that this is a used item. *Please note that this item is also listed on other sites, so it may be sold out. - Manufacturer: Kenford - Product Name: Kouchou Souryuu 630 - Total Length: Approximately 630m - Number of Sections: 14 - Weight: Approximately 268g - Tip Diameter: Approximately 0.8mm - Butt Diameter: Approximately 27.2mm - Closed Length: Approximately 56.5cm - Resin Used: Epoxy Resin - Material: Carbon (Approximately 80%) Thank you for viewing.
