Thank you for viewing. This is a wind chime, a shell chime. I purchased it in Okinawa, and I'm selling it to organize my belongings. (As the photos show, the shells have varying degrees of transparency depending on their thickness.) The shells make a pleasant, cool, and soothing sound that is very relaxing. Please consider purchasing if you understand that this is a used item and if you are interested in interior decor. Returns are not accepted. Instant purchase is welcome. Please ask any questions in the comments. Musical instrument Interior Healing Children's room Kids
