316LVM surgical steel and metal alloy Austrian crystal Claw-set N/A Daith, helix, forward helix, tragus, lobe, septum, nostril, and more! The PREMIUM Butterfly Segment Ring 16g is 316LVM surgical steel, so it's completely hypoallergenic! Surgical steel goes through a low carbon vacuum melting process to remove nickel, one of the most common metal allergens. Please note: the gold or rose gold PVD can irritate if you have metal sensitivities. We recommend wearing the steel or blackline options instead. Hinged segment rings give a seamless ring look without the work of trying to click a loose segment in. If you're new to body jewelry, that's how the regular segment rings work. Imagine a , but instead of a bead, it's a little curved bar. This just clicks open, slide through the piercing and click it closed. It's that easy! The charm is made of 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, it is recommended that metal alloy jewelry be cleaned often and not worn in moist/sweaty places. This piece is a favourite for almost any piercing (like we said before). Let's look at a few examples: daith, helix, forward helix, tragus, lobe, septum, nostril, and so many more than we can list! Show us where you chose to wear yours with #BodyModsFamous on Instagram.
