I bought a large quantity for eel fishing, but I'm selling the ones I can't use. I think it's a better deal than buying sinkers normally. I originally wanted to buy turtle-shaped sinkers, size 25, but since it was about the same price as just the sinkers, I thought it was a good deal and bought them. There were no instructions for the rig, so the details are unknown. I'll list the features below, so please use them as a reference when making a purchase. Please note that I do not plan to offer any discounts. 【Description】 ① Rig length: 50cm ② The top end has a snap swivel, and the bottom has a swivel. ③ Turtle-shaped sinker, size 25 ④ Plastic branch line balance (I don't really understand it?) included ※ I remove and use it when eel fishing. ⑤ Main line is green fluorocarbon, size 8 (in my opinion). ⑥ Each set is individually packaged.
