Make an instant pendant for that special someone even if that is you.
Price is for 1 complete diy add-a-bead, removable end, pendant or earrings holder (bar #3 - the shorter gold holder). The top of the holder, which has the round loop attached, unscrews allowing you to add your beads. Screws back on for you to add to a chain, or earwires, for an instant necklace or pair of earrings.
One photo shows the blank beadable pendant holder while another shows a finished pendant (for your reference only). These are an alloy base metal so it is suggested not to get wet. Each holder is ~1-1/2" from end-to-end leaving ~1" beading space for beads - the rod is ~1.2mm thick. Photos are enlarged to show detail.
There are plenty of free on-line measurement converters should you need one.
