The Serpentine Charm Lock is a flexible component that can be used to create shawl cuffs, jewelry, or other creative closures that can accommodate decorative charms or be used without additional adornment. While we pair the Serpentine with our Snap-on Cuff Straps to create elegant cuffs that work for knitwear and wrists, they work equally well with our Simple Snap Double-wrap cuffs.
