This necklace is (the tag especially) is reminiscent of those old days and i've used a couple of other things for more focus and to grab your attention and to also catch your eye!
What's been used is a round metal key tag with the number "1531" and i've also used a silvertone skeleton key and for an attention grabber, i used 8mm glass faceted ab beads and also threw in a metal spacer.
Also added is a nice asian brass pendant and bronze colored chain and the whole piece fastens with a clasp.
The length of this necklace is 20 inches.
Thanks for looking!
