The finished condition is very good.
Heavy metal.
However, it is difficult to produce a nice ping sound.
When separated in the combined state, it splits into three parts, so be careful.
When removing it, there are a total of 8 small beads placed on the slide, 4 on each side of the central structure. If you disassemble it incorrectly, there is a risk of losing the beads, so remove them slowly and carefully.
The structure is such that when it slides, it impacts the small tuning fork with the bead in the middle, making a ping sound.
To produce beautiful sounds, you need to practice.
The price is high, but I'm not sure if it's worth it.
