Please read the profile before purchasing. This is a conductor's bag. It's an old item. I think the retro feel is nice. Size: Height: Approximately 20 cm Width: Approximately 25 cm Please refrain from purchasing if you are concerned about minor details. There are two instances of disappointment: One is that the seller did not respond for several days, and after contacting the administration, a negative review was left after the transaction was completed. The other is that I overlooked the fact that some of the contents of the book were missing due to my mistake. I will strive to ensure that this does not happen again.
