Made with #120 nylon leader! This is a genuine setup! Since it's nylon, the bite is excellent! It has a proven track record of lifting up to 35kg, so I think 40kg is no problem at all! A swivel is attached at the end. I will change the weight number, glow-in-the-dark rubber, hook size, and manufacturer according to your order! Please tell me the size you want in the comments! The price will vary depending on the size, starting from 1000 yen. Please refrain from purchasing if you are sensitive to handmade items.
