The captive hoops in this collection are made out of type-2 commercially pure niobium and feature a captive bead made out of nickel-free, tarnish-resistant Argentium silver. These are the tiny versions of the designs, and they work well for septum, conch, tragus, helix and daith piercings. They function the same way as the larger design sizes, only the size of the bead is smaller.
