316LVM surgical steel and metal alloy Austrian crystal Claw-set External Nipple Each piece is sold individually. The Claw-Set Heart 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. 316LVM surgical steel is a low carbon vacuum melted. This process sucks the nickel from the metal. Nickel is a common cause of metal allergies. Please note: this process cannot remove all the nickel. As a result, a small number of people react to 316LVM surgical steel. If this is you, we recommend our titanium body jewelry. Otherwise, 316LVM surgical steel is great for people with metal allergies. The yellow and rose gold options are PVD. PVD is more durable and therefore lasts longer than traditional plating. However, the plating may irritate metal allergies. 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.
