Wood or Nut Buttons Necklace 4 strands with Brass beads 16 inches, expands to 19 inchesI'm not sure if the buttons are made of wood or possibly a nut or maybe even a coconut. The bigger buttons are about 3/4" wide. The length is about 19" with the expander used. The longer strand is about 3" longer. It hangs down maybe 3" from the top strand. You could twist the strands a bit to adjust the appearance.
