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. 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.
