Blackline titanium and metal alloy N/A External 7mm feather Lobes, helix, tragus, and more! Each piece is sold individually. The Blackline Small Feather Cartilage Stud is a high-quality piece designed especially for cartilage piercings. Put this stud through your piercing from the front and screw the bead on. The bead is more secure and comfortable than a traditional earring with a butterfly backing. The Blackline Small Feather Cartilage Stud is blackline titanium, so it's completely hypoallergenic! Blackline is a titanium carbide PVD coating. PVD stands for Physical Vapour Deposition. In other words, the titanium carbide deposits onto the metal as a vapour. As a result, the titanium looks black. This coating is 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. This piece is 16g. 16g is the standard size for a cartilage piercing done by a needle. However, if your piercing was with a gun, your piercing may be too small for this. You can shop our for options that will fit you. This stud is a favourite for cartilage piercings (like we said before). Here are a few examples: helix, tragus, flat, and even ear lobes!
