PVD 316LVM Steel N/A Septum Each piece is sold individually. The Blackline Septum Curly Mustache Tusk can be worn in septum piercings as a dramatic statement piece. This tusk is 316LVM surgical steel, so it's hypoallergenic! 316LVM surgical steel goes through a process called low carbon vacuum melting. The process sucks the nickel out of the steel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of nickel. As a result, a small number of people react to it. We recommend our anodized, blackline, or untreated titanium body jewelry if this is a concern for you. Blackline is titanium carbide Physical Vapour Deposition (PVD). In other words, titanium carbide vapour deposits onto the metal. As a result, the metal looks black. This process doesn't affect the hypoallergenic status. This tusk is 12G-8G and not threaded. This means the tusk is a solid piece, so you don't have to to get it in. Pieces of jewelry like this are fun to get inventive with! It's designed to be worn in a septum but could be worn in lobes and other piercings as well. Just be careful not to poke yourself with it!
