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 Cross + Chain Hoop Tunnel Hangers are a matte black silicone and gold PVD over 316LVM surgical steel and metal alloy. The surgical steel goes through a low vacuum-melting process to remove nickel, 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 chance those with severe allergies will react. The gold PVD is more durable and therefore lasts longer than traditional plating. Some people react to this plating. If you are worried about metal allergies, we recommend looking at our anodized, blackline or plain titanium jewelry. The matte black is a silicone finish and must have the proper care. Scratching or damaging may cause the jewelry to 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.
