This is a small steel drum, approximately 7.5cm in diameter and 4.5cm in height. I had it displayed in my room as interior decoration for a while. It has been cleaned of dust, etc. When struck, it produces a beautiful sound reminiscent of a suikinkutsu (a type of Japanese garden ornament). Although it is a musical instrument, it is small, so the sound is also quite quiet. It might be pleasant to play in a quiet place. I have not done things like dripping water on it, as seen online. It's inexpensive, so how about trying it out? As shown in the fifth picture, there is some dirt. Only the tongue drum is included.
