Zipper necklaces, by Vanessa Yanow, are made from SWISS zippers. They zip up to become chokers, down to classic lengths, or you can just leave them somewhere in between. Each necklace has a hand blown, one-of-a-kind, borosilicate (aka. Pyrex) charm that hangs off of the zipper pull. All of the charms are like capsules that contain different objects.
