The Coiled Snakes Tunnel Hangers are 316LVM surgical steel. This grade of surgical steel is preferred for body jewelry because it is low vacuum-melted to remove the nickel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of the nickel, however. As a result, there's still a small chance those with severe allergies will react. If you are worried about metal allergies, we recommend looking at our anodized, blackline or untreated titanium jewelry. Titanium is biocompatible and hypoallergenic. It's what doctors use for surgical implants because of these reasons. The coiled snakes have an antique finish to the steel. This antique finish can come off with jewelry cleaner. 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. Show us how you styled these earrings with #BodyModsFamous on Instagram.
