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 improved and manufactured these parts, and I have repeated field tests, so you can use them 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. Previously, someone falsely requested a photo of my parts and, without a response, on a certain day, they made copies for sales purposes and listed them. They only copied the shape and fixed the spring's moving parts with glue. They don't understand the meaning of the spring (lol). Please take a good look at the differences between the original and the copy before purchasing. 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.
