Sound-Producing Modification Unit A, Improved Version ver2 High-quality components produce excellent sound quality from the initial movement, even with weak tension. I, the creator of the Yaen (squid jig) have improved and produced this unit, and have repeatedly tested it in actual fishing, so you can use it for a long time with peace of mind. Loud sounds can give squid a sense of discomfort through the sound transmitted from the fishing line, requiring strong tension and causing the core components to wear out quickly, leading to many disadvantages. I was the first to come up with and improve these components and list them for sale, and because of these facts, I will explain the truth as the way of listing the components is dirty, such as complaining about the components. On one day, after being falsely asked to upload photos of the components and receiving no response, they copied and listed them for sale in a factory for the purpose of sales because they couldn't make them themselves. Only the shape is there, and the spring movement part is fixed with glue. They don't understand the meaning of the spring (lol) Do you trust a liar who makes excuses? Please take a good look at the differences in the springs. I am listing these products while considering various things from the buyer's perspective, especially the price. If you remove the spring from the 5-pin photo, it becomes difficult to attach and tends to stretch and come off, so two substitute tubes are included as a bonus. If you use them instead of the spring, you can easily remove and reattach them many times.
