I bought this a few years ago and listened to it two or three times, after which I put it on a shelf and left it there. It's a decorative music box from Sakura Castle in Izu. It looks beautiful, and the sound is also beautiful. It plays without any problems, just like when I bought it. I haven't opened the lid, so I don't know if it opens. The size of the music box case is approximately 9 cm in diameter and 3.2 cm in height. There is no outer box. Thank you. - - Design: Circular transparent plastic - Shape: Music box in a circular case Thank you for viewing. Main material... Plastic
