Adam, a higher quality Vintage Asian Drum maker.
I found this in my storage room.
Has been sitting unused for probably 20 or more years.
$50 as is (but all works perfectly) Cash upon pick up!
It has a little piece of plastic attached to a nylon cord inside that bounces around when the drum is hit.
(look at photo)
And this is how it came?
Creates a unique sound, and that's why I purchased it.
Used it for one song on a session a real long time ago.
Has sat in case ever since.
