Sound-producing part B, lightweight improved version ver2 Good parts produce good sound quality from the initial movement even with weak tension. As the creator of the Yaen, I have been making improvements and conducting actual fishing tests, so you can use it for a long time with peace of mind. Loud sounds give squid a sense of discomfort from the sound of the line, and strong tension also quickly wears out the core of the parts, resulting in many disadvantages. I was the first to come up with and improve the parts and put them on sale. I will explain the facts because I am annoyed by the unauthorized use of photos of products that are not in hand, complaints, excuses, and sneaky methods. One other person and I were asked to upload clear photos at night, but there was no response. One day, they copied and put the product on sale at a local factory for the purpose of sales. Only the shape is there, and the spring movable part is fixed with glue. They don't understand the meaning of the spring (lol). Do you trust liars and people who make excuses? Please take a good look at the differences in the springs. I am selling these products by considering various things from the buyer's perspective, especially the price. In photo 5, if you remove the 5-pin spring, it becomes difficult to attach and it stretches and comes off easily, so I will include two tubes as a substitute. If you use them instead of the spring, you can easily remove and reattach them many times.
