14kt gold-filled. Measures 1.5" in length, made of 26 gauge wire.
Headpins are wires that feature a flattened end designed to hold a bead in place at the end of the wire. The excess wire can then be made into a loop and added as embellishment to earrings, the end of a necklace, or even act as a centerpiece.
26 gauge wire is reserved for beads with very small holes. This includes precious stone and some Indian stone. Wire wrapping the loops closed is recommended.
