I have a small, thimble-shaped silver box that I found with my
grandmother’s things. It has a tiny arrow pointing to to the
direction to unscrew it so that the little bump locking it closed
can travel down a small groove and then the top pulls off of the
bottom and it opens up. In script on the side of it the words “My
Identity” are engraved. It has a little silver loop on top and it
was hanging by a short piece of blue embroidery thread.
Anyone know what this is??
