Criss Cross Zipper Necklace by Kate Cusack. The Criss-Cross Zipper Necklace features a repeating X motif that gracefully graduates in size from the clasp to the center. It is a hand-made piece of statement jewelry that sits close to the neck and will compliment many clothing-necklines. The shiny-silver teeth are plated nickel and the fabric is a poly-cotton blend. The necklace clasps with two hidden magnetic snaps which are signed by Kate.
