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 Vitrail Demon Tunnel Hangers are 316LVM surgical steel and metal alloy. The surgical steel is low vacuum-melted to remove nickel. Since nickel is one of the most common causes of metal allergies, this process makes the steel hypoallergenic. This process can't remove 100% of the nickel, however. As a result, there's still a small chance those with severe allergies will react. If you worry about metal allergies, we recommend our anodized, blackline or untreated titanium body jewelry. Titanium is biocompatible as well as hypoallergenic. 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 tunnel hangers with #BodyModsFamous on Instagram.
