Sound-producing part B, lightweight improved version ver2 Thank you for your high praise, repeat purchases, and purchases of items like Yaen. This sound-producing part is an original, unlike any other, that I created by first considering things from the buyer's perspective. Good parts produce good sound quality from the initial movement even with weak tension. As a Yaen creator, I have improved and produced this part, and I have repeated actual fishing tests, so it is safe for long-term use. Excessively loud sounds can give squid a sense of discomfort from the sound of the line, and strong tension also quickly wears out the core of the part, leading to many disadvantages. Please take a good look at the differences, such as the spring. Production labor + material costs = buyer's perspective = I am listing at reasonable prices, considering various factors. If you remove the spring from the 5-pin photo, it becomes difficult to attach and tends to stretch and come off, 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.
