This is a wind chime-like strap with a matryoshka design. I think it's made of plastic. It makes a slight sound when shaken. Since it was stored with other straps without being put in a bag, there are some places where the paint has peeled off. I think it's cute as interior decoration too. Please consider it if you like. Length: With string: 16cm Width: Top wind chime: 2cm Bottom wind chime: 1.5cm Shipped by post.
