This is a bongos stand, maker unknown (probably Pearl). I listed it as junk, but all parts function (I think it's quite old). The advantages are that it's lightweight and has a part to support the bottom of the bongos so they don't tilt when struck. If anyone wants it, I'll give it away. ※Similar ones were trading for around 8000 yen, so I'll sell it for less than half price.
