Thank you for looking. These are handmade iron fishing weights. 20kg tensile strength test. The strength is such that the swivel will break when pulled by two adults. *The images are stock photos. Since these are handmade, there may be minor rust, variations in swivel color, and slight weight discrepancies. Please comment if you would like multiple. Discounts are not possible as shipping is included. Thank you. Handmade Fast sinking weight Sinkers Boat fishing Deep sea Electric Reel Kinme Akoudai Sinker Weight
