The exterior is porcelain. #P.S. I LOVE# YOU # is a song, ##it's one of the Beatles' songs. #❣️#Hey Jude#❣️ #MUJIC＃BOX# is written on it, so #music box tested## It has been played several times and still plays beautifully. The English text in the latter half of the sentence clearly states that the copyright of the song exists. I think it's a rare item. #Heart-shaped #8.5 x 8 size# #Square Hey Jude 9 x 8 size# #Both are music boxes. When you turn the screw-type music box, the song plays. I bought two before, and the song plays when you turn the screw. #I will sell them as a set of two# I #like collecting and displaying #rare and unusual items. I want you to listen to the music, but I don't know how to upload a video.
