Here is a surface piercing in a location sometimes referred to as an "anti eyebrow" piercing.
These are not service anchors, it was done with a surface bar (a bar with a right-angle terminal at both ends) from Anatometal.
Note that the rise of the surface bar terminals provide adequate space for the tissue yet the flat-back 4mm white Swarovski crystals still lay flat.
This piece has been done with proper jewelry. Sadly, other piercers are still suing curved barbells. Curved barbells put unnecessary pressure on tissue and very rarely heal.
