When you go thrift shopping, you’re bound to come across things that you’ve never seen before. This OP found a metal tube with a screw-on cap that had no numbers or letters engraved on it. There was even a small hole at the tip of the cap. What was it exactly and how did one use it?
Thanks to internet detectives, the OP found out that they were now the proud owner of an antique needle case. These cases held sewing needles and were designed to hang from a belt. Considering how easily needles seem to get lost, this makes absolute sense!
