This is a key-shaped bottle opener that brings good luck. It's made of iron and painted black (rust-proofed). I'm selling it to organize items I've kept at home for many years. I believe I received it as a commemorative item over 50 years ago. Although it's unused, it's old, so there is some rust and dirt on the box. Please check the images and consider purchasing. It would be great for those who like Showa retro items or for display. #BottleOpener #IronMade #ShowaRetro
