Charlottes are beads that have been cut with facets in them, to give them a reflective property.  These Charlottes are Czech made size 15's, and are very small - roughly equivalent to the Japanese size 18.  Excellent for adding subtle glamour to projects such as beaded Rivolis and cabochons.  Many of the colours below are not widely available.  The quantity shown in the photos is not intended to represent the amount in a 5g packet.
