This is a beautifully handmade, stamped Sterling round pillbox by Arnold Blackgoat. We see so very few of these nicely made boxes these days. This is buffed to a high-polish shine. The fourth photo shows a practical use for this as a container for legal medical marijuana (medicine not included with box).
Hallmarked BLKGT and stamped Sterling inside the box.
Size: 1 13/16" diameter; 7/8" tall from bottom of box to highest point on lid
