2mm BioPlastic Flat Black Disc Top for 18g PTFE Nose Screws & 14g-16g BioPlast Labret Studs (Price Per 1)

These 2mm BioPlast black disc tops work with our 14g and 16g PTFE labret studs and our 18g BioPlastic nostril screws, all of which have the same size holes. You can use these black BioPlast tops with any labret piercing, nostril piercing, or other lip piercing in which you prefer to wear a BioPlast stud. They're the perfect tool for creating a black mole on your upper lip, if you have a Monroe piercing, but they make a cool addition to any facial piercing.

These 2mm BioPlastic flat black disc tops for PTFE body jewelry are sold individually (price per 1) and separately from our BioPlast labret studs and PTFE nostril screws.
