An old key, possibly made of iron. It's quite old, from France, and was supposedly a very valuable key that was actually used (according to the seller, so take it with a grain of salt). I bought it at an antique market, so there are no guarantees or certificates. I was displaying it as interior decoration. I was into antiques at the time and bought it for 20,000 yen. How about it for antique lovers, interior decoration, or as a photo prop? Please check my profile.
