Sound Production Modification Unit A Improved Version ver2 This sound production part is an original that I created by considering various things from the perspective of a purchaser, and it cannot be imitated by others. Although the shape is almost the same and sound can be produced regardless of where it is made, the difference appears after use depending on the skill of the person who assembles it by hand. Even if defective products are produced, what's the point of being more secure than self-made products with factory production? Check the reviews too! Many people have replaced parts after consulting about problems with other people's parts, and my parts are highly praised as being good. Good parts produce good sound quality from the initial movement even with weak tension. As the creator of Yaen, I have improved and produced these parts, and I have repeated actual fishing tests, so they are safe for long-term use. 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. Please take a good look at the differences, such as the springs. Production labor + material costs = purchaser's perspective = I am listing these at a reasonable price, considering various factors. If you remove the spring from the 5-pin photo, it becomes difficult to attach and it stretches and comes off easily, so I'm including two spare tubes as a bonus. If you use them instead of the spring, you can easily remove and reattach them many times.
