Strike it with your hands or shake it to create a rhythm [Jingle Stick NINO13R]
The "jingle" refers to the bells of a tambourine, and the "jingle stick" is shaped like a straightened stick, hence the name.
The tone changes depending on whether you shake the bells vertically or horizontally, so you can enjoy playing it by striking it with your hands like a monkey tambourine, or holding it horizontally to create a rhythm like a shaker.
It can be used in a variety of situations, such as livening up concerts and karaoke!
