NeoMetal Side Set Lavender Opal Cabochon Curved Barbell THREADLESS

This barbell features synthetic Opal Cabochons securely set by bezel. No glue is used or even required for this jewellery ensuring the best lustre is shown for each gem. A lightweight and adorable little curved bar - perfect choice for a dazzling rook or eyebrow piercing.

As with all faux gemstones, each one is unique so please expect variation from that shown in the images.

Originally pioneered by NeoMetal, the push-fit design is a secure option for a reliable wear in a piercing. The threadless post on the end creates a tight fit inside the curved post. (This is the only instance when threadless pins are not bent for fitting).  To remove or insert, just tug gently on the removable end and it will come apart from the post.

NeoMetal's implant grade titanium is lightweight and nickel-free and a perfect option for long-term wear in new and healed piercings.  Each piece holds a lifetime guarantee against defects in workmanship!
