316LVM surgical steel and metal alloy Austrian crystal Adhesive-set External Nipple Each piece is sold individually. The Jewel Edge 3D 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. The Jewel Edge 3D Nipple Shield is 316LVM surgical steel. 316LVM surgical steel goes through a process called low carbon vacuum melting. The process sucks the nickel out of the steel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of nickel. As a result, a small number of people react to it. We recommend our anodized, blackline, or untreated titanium body jewelry if this is a concern for you. Otherwise, 316LVM surgical steel is an excellent option for people with 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 stones are Austrian crystals. We love Austrian crystals because, with proper care and cleaning, they never lose their sparkle like other similar stones. Show us where you wear yours with #BodyModsFamous on Instagram.
