.925 Sterling Silver InvisiNip? CZ ZIPPER Dangles (Each Sold Separately). Stunning craftsmanship, these are very original items. Each Nipple Ring is comprised quality strands of prong set Cubic Zirconias with a cool sterling silver Zipper! InvisiNip? Nipple Rings are seamless, hardware free Nipple Rings without threads, made from PTFE acrylic. The hollow barbell allows the insertion of two sterling silver rods that hold the nipple rings together. These items are especially popular as they are less bulky than conventional barbells with no awkward steel balls and bars, and the PTFE barbell is flexible allowing for dramatically increased comfort. Due to the material used in InvisiNip? Nipple Ring barbells, the length of the barbells can be reduced to custom fit any nipple size. No more awkward looking jewelry, just trim down the barbell with sharp scissors to fit your piercing perfectly!
