EUC Vintage Japanese Trench Case/Make-up or Jewellery Case

Looking online, this could also be called a "Train Case." This black case (dimensions on tag - 30x20x17) was bought in a vintage shop in Japan decades ago. I thought it was so retro and cool. Someone used it long ago. On the inside, the satin material has a few small stains (see pictures), but its ruffled look around the mirror is gorgeous. The bottom of the case has a few minor scratches (see pics). The tag shows it came with a tray, but I never saw it. The inside mirror is perfect except for what looks like some glue residue in the bottom right-hand corner. I checked the lock and key. It works. I never got around using it because I didn't want to damage it. It has sat collecting dust for too long. It is in excellent condition. It is truly unique since it came all the way from Japan.
