316LVM surgical steel N/A Internal. Daith and septum. Wear a circular barbell in surface piercings for the look of the heart shape bead. These are super easy to wear. Like a straight or curved barbell, just twist off a bead, put the jewelry in and twist the bead back on. The Surgical Steel Heart Circular Barbell 16g is 316LVM surgical steel. This grade of steel is hypoallergenic because its low carbon vacuum melted. This process sucks the nickel out of the metal. Nickel is one of the most common causes of metal allergies. Please note: this process does not remove all nickel. As a result, a very small amount of people react to 316LVM surgical steel. If this is you, we recommend our jewelry. This piece is a favourite for almost any piercing. Here are a few examples: daith, rook piercings, vertical labret, snug, jestrum, eyebrow, and so many more than we can list!
