Total length: approximately 28mm (Equivalent to size 5 to 6) Strength: approximately 16kg I found these while organizing the warehouse of my family's fishing hook shop. Since the manufacturer is unknown, I am offering them at a low price. The strength is based on information found online. Please be aware that this information is for reference only. Although they are new, they have been stored in a home warehouse for a long time, so I have listed the product condition as "Like New". The contents are clean, but please refrain from purchasing if you are sensitive to such matters, to avoid any issues. *I am also selling various other fishing tackle items. If you wish to purchase multiple items, please select the combined purchase option. Thank you very much. *I have set the shipping time to 4-7 days, but I will do my best to ship as soon as possible.
