Charms can be worn on most styles of jewelry. Smaller charms are best worn on ring styles (Simple Seam Ring) but longer, chain style charms can be worn on post style jewelry as well.
You're welcome to reach out to us if you have any questions about suitability for your piercing/jewelry.
If you are unsure of the sizes needed it is never a bad idea to consult a professional piercer to confirm both gauge (thickness) and diameter for your piercing. Professionals in your area can be found by visiting www.safepiercing.org.
