It came out of a chest of drawers, placed in a paper bag as shown in the photo. It is 21 centimeters long, 1.5 millimeters wide, and the loop is 2 centimeters long. I thought it was unusual, with a reversible design, perhaps fashionable at the time. I don't know what era it's from, but it's in beautiful condition, as if it was just purchased. I hope someone who can use it will appreciate it.
