These tunnel hangers have a hinged clasp so you can comfortably wear them in the ear or through a (hence the name). Just pop them in and go! The Black Rose Tunnel Hangers are a matte black silicone over 316LVM surgical steel and metal alloy. The surgical steel goes through a process called low vacuum-melting to remove nickel. Since nickel is one of the most common causes of metal allergies, this process makes the steel hypoallergenic. This process cannot remove 100% of the nickel, however. As a result, there's still a chance those with severe allergies will react. If you worry about metal allergies, we recommend looking at our anodized, blackline or untreated titanium body jewelry. Titanium is biocompatible and hypoallergenic. Doctors use implant grade titanium for surgical implants for these reasons. Finally, the black silicone must be handled with care. If it gets scratched or damaged, the hangers may start to peel. 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 wear these earrings with #BodyModsFamous on Instagram.
