Sound-producing modification unit A, improved version ver2 Good parts produce good sound quality from the initial movement even with weak tension. The author of the Yaen (squid jig) has improved and manufactured this, and has repeated actual fishing tests, so it can be used 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, which has 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. 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. I and another person were asked to upload clear photos at midnight, but there was no response, and one day, a copy was put on sale at a town factory for the purpose of sales. Only the shape is there, and the spring movable part is fixed with glue. The level of workmanship doesn'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. Photo 5: If you remove the 5-pin spring, it will be difficult to attach and will easily come off, so two tubes are included as a substitute. If you use them instead of the spring, you can easily remove and reattach them many times.
