How Pandora's bracelets & necklaces work:
(US Patent No. 7,007.507)
Pandora beads & charms are threaded.
Bracelets & necklaces have a threaded end that each bead or charm screws over.
Bracelets & necklaces are divided into 3 sections, each separated by a threaded segment.
Thus beads & charms can be positioned along the length of the chain.
Clips can be snapped over the threaded segment, locking the beads into a section.
