PVD titanium and metal alloy Austrian crystal Adhesive-set External Nipple Each piece is sold individually. The Elephant Nipple Shield is a high-quality piece. The design best suits nipple piercings. To wear this jewelry, start by lining the shield up with your piercing. Slide the barbell through the loops on the shield and your piercing. This shield is a great alternative to like captive bead rings or circular barbells. PVD is more durable and therefore lasts longer than traditional plating. However, the plating may irritate metal allergies. We use PVD over titanium because of its porosity. Being porous means the PVD holds onto the metal better, and as a result, lasts longer. In other words, this is a double whammy of durability. If you have metal allergies, we recommend 316LVM surgical steel or our blackline, anodized or untreated titanium jewelry. The charm is a metal alloy, which is ideal for casting and makes them perfect for jewelry with fine details. Many people have sensitivities to these alloys and may react. Metal Alloys with a PVD coating can help negate this reaction, but they may still irritate those with the strongest sensitivities. To avoid turning green, metal alloy jewelry is recommended to be cleaned often and not worn in moist/sweaty places. The soft blue stones are Austrian crystals. We love Austrian crystals because, with proper care and cleaning, they never lose their sparkle (unlike other similar stones). Show us where you wear yours with #BodyModsFamous on Instagram.
