Typically what you will find for eyebrow piercings are curved barbells or ball closure rings or straight barbells.
Piercings anywhere along the ridge of the eyebrow.
These are usually vertical but may be angled slightly.
The final look of your eyebrow piercings will depend not only on your eyebrow jewelry choice,but also on the placement of the eyebrow rings ( or other jewelr piercings like barbells).
