A fuurin is a Japanese-style wind chime. It shaped like a cowbell, with a ceramic or glass cup with a ball suspended inside. There is often a piece of paper that dangles below the ball.
This fuurin is ceramic with chibi Shao, Ruan, Rishu and Kiryuu. Little fish and bubbles, with the words "Mamotte Syugogetten!" trailing near the end. The paper that hangs from the bottom also has the chibi characters.
I think these chimes are used during the summer. It would be great to hang outside, but it could mess up the little paper tag!
