Charms are a great way to add some extra texture and movement to your set-up. Charms can be added to hoops in healed piercings, and look great in helix, rook, and lobe piercings. Our lightning bolt charm measures (approximately) at 4mm in length, and the o-ring diameter is 3mm, making it suitable for 18g, 16g, and 14g hoops. Our jewellery is sold individually, not in pairs. If you need a pair of these please order two.
