A black bead necklace is useful for so many things.  Flappers, go-go dancer, torch singer and more.  However, each costume needs a different size necklace.  Why buy multiple different size necklaces when you can buy a set of 6 add a strand necklaces.  Each necklace is 32 inches overall length and has a clear elastic cap that joins the two section of bead.   Simply uncap one end of two necklaces and snap back together.  Great for costumes, holidays, parties, and team colors.
