Tube is 14mm long x 7mm thick, with a 2mm threading hole.
Easily hang a pendant or beaded design onto these thread on bails. Attach via a jumpring if necessary. Do ensure your pendant will face the front when attaching - some pendants need to jumprings to have it face the correct way.
These bails make it really easy to make your own leather necklace or choker - or you may want to hang a small charm off a bracelet. Thread them into place, then bead up each side, or you may want just the bail with the pendant at the front.
The pieces are brass based metal with high quality plating.
