Vintage brass stamping of a shield with a sunny beach scene claiming NEW JERSEY.
No loops or holes for stringing so you'd have to use some sort of adhesive to use these pieces in your project. However if you have a tiny metal punch, these can easily be made into charms by punching a hole and attaching a jump ring.
You could further embellish these using inks/enamels/paints/etc.
These are SMALL so get your rulers out if you're unsure offhand how small these are. Measures 5/8" x 9/16"...or just over 1/2" in both directions.
