These white color round beads are made from natural bone. The slight variations in colors and shape of the beads will make them a fun addition to your beading project. Look carefully and you will see that each bead is unique. Individual beads measure 4 x 4-5mm diameter with approximately 85 beads on each 15" strand. Use them as spacers or accent beads. Current stock may not have black cord and length is somewhat shorter than pictured. The rustic character of these beads is sure to add an authentic touch to your jewelry designs!
