This item was purchased by my 70-year-old parent around the age of 20, apparently to give to someone, but they were unable to give it away and kept it until recently. It's about 50 years old, but it's in fairly good condition, so I got permission to list it. The spring inside feels a little weak. The closing mechanism works fine. The word "GERMANY" is stamped on the opening part. They said it should be made in Germany. The corners are slightly pointed. There are no instructions, box, or bag. In the seventh photo, I tried putting a business card inside for reference. If anyone is interested, please consider it.
