These unique Hanging Horn Stars have a flexible insertion gap that pushes back to a closed position so they won't fall out. The star earrings are hand made in Indonesia from natural water buffalo horn, so some variation is present from the pair shown in this image and also from piece to piece within a pair. Size may vary up to 1/2 size. For example, if you select a 12 gauge pair of earrings, the actual size may be larger than 12 gauge but smaller than 11 gauge.
