RYUGI Combo Stopper 40 pieces per package.It's not just a matter of increasing the number. The number of pieces is set assuming that it will be used in combination with 2 or 3 pieces (combination).By using it continuously, it is possible to fix the sinker quite strongly. I want you to adjust to the best fixing force depending on the situation such as the thickness of the line and the weight of the sinker.Being able to continue to use the rig without stress will lead to fishing results.
