I purchased this but am selling it as I haven't had a chance to use it. There are scratches on the outside of the box, but the contents are unused. This is a convenient tool for FG knots. Knot assist tools are essential to prevent lure loss and mistakes that cause PE and leader lines to break. It costs 3500 yen at the fishing tackle store, but how about half price? Thank you. #KNOT ASSIST #ASSIST 2.0 #ノットアシスト2.0 #Fgノット Product Description KNOT ASSIST 2.0 for easily tying FG knots between PE line and leader, lightweight and convenient to carry.
