Despite the negative many ratings I decided the rain rattle to order. And that was worth it. A really beautiful crafted toys / musical instrument. With me is sharp-edged screw no trace. Since the rattle is made entirely of wood / acrylic glass results in a very valent overall picture that hopefully is also very durable. The colors are beautiful and the sound is wonderful, but to me a bit too loud. But here convinced the rattle: sometimes try if I can replace the metal balls through wooden beads. The open screw should allow actually.
